Authentication Bypass

Integer overflow in Linux kernel's IPv6 IOAM (In-situ Operations, Administration, and Maintenance) trace functionality allows remote unauthenticated attackers to trigger buffer overflow conditions. A crafted IOAM trace packet with specific schema configurations causes an 8-bit integer wraparound that bypasses buffer boundary checks, enabling memory corruption with potential for arbitrary code execution at kernel privilege level. CVSS scored 9.8 (Critical) with network attack vector, though EPSS score of 0.02% (7th percentile) suggests minimal observed exploitation activity. Patches available across multiple stable kernel versions (5.15, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, 7.0) via upstream commits, indicating vendor-prioritized remediation without confirmed active exploitation.

Authorization bypass in SEPPmail Secure Email Gateway versions prior to 15.0.4 enables remote unauthenticated attackers to access privileged GINA UI endpoints without authentication. The vulnerability (CISA reported by Swiss NCSC) affects core access control mechanisms with CVSS 9.3 critical severity, allowing complete system compromise through network-accessible administrative interfaces. No active exploitation (CISA KEV) or public exploit code identified at time of analysis, but the network-accessible attack vector with no authentication barrier presents immediate risk to internet-facing deployments.

Unauthorized cross-tenant access in Apache CloudStack 4.21.0 through 4.22.0 allows remote unauthenticated attackers to gain full control over virtual machines belonging to other tenants via the Proxmox extension. Attackers exploit a user-editable 'proxmox_vmid' setting that lacks tenant ownership validation and predictable VM IDs to reference and control VMs across tenant boundaries, enabling VM start/stop/destroy operations. CVSS 9.1 indicates critical severity with network attack vector and no authentication required, though EPSS data and KEV status are not available to confirm active exploitation patterns.

Authorization bypass in CashDro 3 web administration panel 24.01.00.26 allows authenticated attackers to escalate to full administrative privileges by manipulating client-side permission controls. The vulnerability stems from reliance on frontend-only authorization checks, with no backend validation of user permissions. Attackers with low-privileged accounts can modify the 'Permissions' field in JSON responses to grant themselves unrestricted access to cash management system controls. INCIBE-CERT has confirmed vendor patch availability, though EPSS data is not yet available for this recent CVE.

Brute-force authentication bypass in CashDro 3 web administration panel 24.01.00.26 enables remote unauthenticated attackers to gain full administrative access. The system accepts numeric PINs without account lockout mechanisms, a legacy design from 2012 POS integrations. Successful exploitation grants access to confidential configuration settings with high impact to confidentiality and integrity (CVSS 9.3). No public exploit identified at time of analysis, though exploitation is trivial given the vulnerability class. Patch available per vendor advisory from INCIBE.

Authentication bypass in UltraDAG Core blockchain allows remote unauthenticated attackers to drain all pocket-derived sub-addresses on smart accounts, completely bypassing vault delays and daily spending limits. The StateEngine fails to resolve pocket addresses to their parent account during policy enforcement, treating virtual pocket addresses as unrestricted accounts. Confirmed actively exploited (CISA KEV). Vendor-released patch: commit fb6ef59 resolves pocket-to-parent mapping before all policy checks. EPSS data unavailable but attack vector is network-accessible with no complexity (CVSS 4.0 AV:N/AC:L/PR:N), making this a critical priority for any UltraDAG deployment using smart account pockets.

Remote attackers can decrypt tenant email addresses and metadata, and trigger denial-of-service conditions in MAXHUB Pivot client versions prior to v1.36.2 via hardcoded AES encryption keys. The vulnerability (CWE-327: Broken/Risky Cryptographic Algorithm) enables complete bypass of data confidentiality controls without authentication due to embedded cryptographic secrets in the application binary. CISA ICS-CERT disclosure indicates this affects operational technology environments where MAXHUB collaboration devices are deployed. No active exploitation confirmed in CISA KEV at time of analysis, though the attack vector is trivially exploitable (AV:N/AC:L/PR:N/UI:N) once the hardcoded key is extracted via reverse engineering.

OpenStack Cyborg allows any authenticated user to reprogram FPGA bitstreams and execute privileged operations across arbitrary compute nodes due to unconditional authorization bypass in multiple API endpoints. Versions before 16.0.1 use rule:allow as the default policy, permitting any valid Keystone token holder-even users with zero role assignments-to perform administrative actions including FPGA reconfiguration via agent RPC. EPSS data not available, but the authentication bypass combined with scope change (CVSS S:C) and hardware manipulation capabilities represents significant risk in multi-tenant OpenStack deployments.

Confidentiality breach in Azure AI Foundry M365 published agents enables remote unauthenticated attackers to access high-value data through improper access control (CWE-284). The vulnerability affects agents published through M365 integration, allowing privilege escalation over the network with no authentication required and low attack complexity (CVSS:3.1 AV:N/AC:L/PR:N/UI:N). Microsoft has released a vendor patch per MSRC advisory. No active exploitation confirmed by CISA KEV, and EPSS data not available at time of analysis.

Remote unauthenticated attackers can exploit a server-side request forgery (SSRF) vulnerability in Microsoft Partner Center to access internal resources and perform spoofing attacks. The vulnerability allows high-level information disclosure with limited integrity impact, requiring no user interaction or special privileges. Microsoft has released a security patch, and while CVSS rates this 8.2 (High), no active exploitation or public proof-of-concept has been identified at time of analysis.

Authorization bypass in Microsoft Teams enables authenticated attackers to escalate privileges across security boundaries and access sensitive information from other tenants or user contexts. The CVSS score of 9.6 reflects a scope change (S:C), indicating the attacker can impact resources beyond their authorized permissions with high confidentiality and integrity impact. Vendor-released patch available from Microsoft Security Response Center. No public exploit identified at time of analysis, with CVSS temporal metrics indicating unproven exploitability (E:U).

Remote code execution in Azure Managed Instance for Apache Cassandra allows authenticated attackers with low privileges to execute arbitrary code across tenant boundaries. The vulnerability involves improper access control (CWE-284) enabling scope escape with complete compromise of confidentiality, integrity, and availability. Microsoft has released a patch per MSRC advisory. CVSS 9.9 (Critical) reflects network-based attack with low complexity, low privileges required, and changed scope indicating container/tenant escape potential.

The Go toolchain's module proxy validation can be bypassed by attackers controlling untrusted GOPROXY or GOSUMDB endpoints, allowing delivery of malicious toolchain versions that execute with developer privileges. When the go command downloads a different toolchain version (via GOTOOLCHAIN, go.mod, or go.work directives), a malicious proxy can serve altered toolchains by exploiting checksum database validation logic that incorrectly accepts empty responses. While EPSS indicates only 1% exploitation probability and CISA SSVC marks exploitation status as 'none', the total technical impact rating and network attack vector (AV:N) represent significant supply chain risk for organizations using non-default module proxies. Vendor patch available in Go 1.26.3 and 1.25.10.

Privilege escalation in FreeScout allows low-privileged agents to reassign conversations to customers in unauthorized mailboxes. The Change Customer modal enforces mailbox-scoped visibility on the frontend search endpoint, but the backend conversation_change_customer action lacks parallel authorization checks, accepting arbitrary customer_email parameters. An authenticated agent with access to mailbox A can forge requests to bind conversations to customers in mailbox B, bypassing tenant isolation controls. Vendor-released patch version 1.8.214 addresses this authorization bypass alongside four related customer visibility vulnerabilities disclosed concurrently (GHSA-mv55-3mgv-fxwr, GHSA-wjw4-8xg6-342m, GHSA-9ff4-mmhv-x6jp, GHSA-674v-r6xp-mvp6). No active exploitation confirmed (not in CISA KEV); CVSS 7.1 reflects network vector with low complexity but requires authenticated agent credentials.

Remote unauthenticated attackers can invoke arbitrary methods in Ivanti Endpoint Manager Mobile (EPMM) via improper access control flaws, enabling authentication bypass and potential system compromise. Affects versions prior to 12.6.1.1, 12.7.0.1, and 12.8.0.1. The CVSS vector indicates network-accessible exploitation with high attack complexity, resulting in high integrity impact and limited confidentiality/availability impact. No active exploitation confirmed via CISA KEV at time of analysis, though the authentication bypass tag and Ivanti's history of targeted attacks warrant elevated monitoring.

Anonymous MQTT access in Yarbo firmware v2.3.9 allows remote unauthenticated attackers on the local network to fully control the robotic lawn mower and exfiltrate sensitive telemetry data. The embedded MQTT broker accepts connections without credentials and enforces no topic-level access controls, enabling arbitrary publish/subscribe operations. No authentication, authorization, or message validation occurs. EPSS and KEV data not available; exploitation requires only network access to the robot's MQTT port (typically TCP 1883).

Hardcoded administrative credentials in Yarbo firmware v2.3.9 allow remote unauthenticated attackers to gain full device administrative access across all deployed units. The CVSS 9.8 critical score reflects the complete lack of authentication barriers (AV:N/AC:L/PR:N), with identical credentials embedded in every device that cannot be changed by end users. No active exploitation has been confirmed by CISA KEV, but a public GitHub repository reference suggests potential proof-of-concept availability. EPSS data unavailable, though the trivial exploitation path (no complexity, no privileges required) indicates high weaponization potential once credentials become widely known.

Privilege escalation in Ivanti Endpoint Manager Mobile (EPMM) allows remote authenticated attackers with low-level credentials to gain full administrative access. Affected versions prior to 12.6.1.1, 12.7.0.1, and 12.8.0.1 contain an improper access control flaw (CWE-284) that enables credential-holding users to bypass authorization checks and assume administrative privileges. With CVSS 8.8 (High) and network-exploitable attack vector requiring only low privileges, this represents a significant risk for enterprise mobile device management environments, though EPSS data and active exploitation status are not available at time of analysis.

Certificate validation in GnuTLS can be bypassed when a certificate chain contains Certificate Authorities with only excluded name constraints followed by CAs with permitted name constraints. Remote attackers can exploit this flaw (CVSS 7.4, AV:N/AC:H) to present invalid certificates that pass validation, enabling man-in-the-middle attacks or service impersonation against TLS-protected communications. The vulnerability affects Red Hat Enterprise Linux versions 6-10, OpenShift Container Platform 4, and Red Hat Hardened Images. No public exploit or active exploitation confirmed at time of analysis, though the technical nature suggests targeted attacks against high-value certificate infrastructure are feasible.

Authentication bypass in GnuTLS affects servers that enable the RSA-PSK key exchange, where the PSK identity comparison treats a username containing an embedded NUL byte as equal to a legitimate truncated username. Remote attackers can send a crafted username to circumvent pre-shared-key authentication and gain unauthorized access. There is no public exploit identified at time of analysis, the EPSS probability is low (0.15%), and CISA SSVC scores exploitation as none - indicating high theoretical severity but no observed real-world abuse.

vm2 NodeVM with nesting:true silently overrides require:false, granting sandbox code unconditional access to require('vm2') and enabling remote code execution on the host via nested NodeVM construction. Applications running untrusted code in a NodeVM configured with {nesting:true, require:false} are fully compromised — attackers can execute arbitrary OS commands as the host process user. Publicly available exploit code exists (proof-of-concept demonstrated command execution via child_process). CVSS 9.1 indicates high privileges required (PR:H), meaning the host must explicitly enable nesting:true, but the severity reflects scope change (S:C) when this non-default configuration is present. Vendor-released patch in vm2 3.11.1 converts contradictory configuration into a runtime error at NodeVM construction time, preventing silent sandbox escape.

vm2's NodeVM sandbox escape allows remote code execution when applications use the common `builtin: ['*', '-child_process']` configuration pattern. An attacker with the ability to submit code to the sandbox can bypass the builtin allowlist by requiring the `module` builtin, then using `Module._load()` to load explicitly excluded modules like `child_process` in the host context. This directly leads to arbitrary command execution on the host system. The vulnerability affects vm2 version 3.10.5, with a vendor-released patch available in version 3.11.0. CVSS score of 9.9 reflects critical severity with network attack vector, low complexity, and scope change from sandbox to host. No public exploit code or active exploitation evidence identified at time of analysis.

Remote unauthenticated attackers can access Google Secrets Manager credentials from unintended GCP projects via crafted requests to Spring Cloud Config servers using Google Secrets Manager as a backend. VMware confirmed this high-severity information disclosure vulnerability (CVSS 7.5) affecting all 3.1.x through 5.0.x versions. No CISA KEV listing or public exploit code identified at time of analysis, but the network-accessible attack vector with no authentication or user interaction required (AV:N/AC:L/PR:N/UI:N) indicates straightforward exploitation once attackers identify vulnerable Spring Cloud Config deployments with Google Secrets Manager integration.

Authentication bypass in free5GC Policy Control Function (PCF) allows unauthenticated network attackers to access Session Management policy control APIs and exfiltrate subscriber identities (SUPI). The Npcf_SMPolicyControl service group omits RouterAuthorizationCheck middleware, permitting OAuth-less access to four policy management endpoints that should require service-to-service authentication. Publicly available exploit code exists. CVSS 8.2 reflects direct network access with no authentication barrier, high confidentiality impact from SUPI disclosure, and low integrity impact from unauthorized policy manipulation. No EPSS or KEV data available, but PoC in vendor advisory demonstrates trivial exploitation against default SBI deployments.

Cross-tenant Insecure Direct Object Reference (IDOR) in Aegra 0.9.0-0.9.6 allows any authenticated user to execute graph runs against other users' threads, exfiltrate full checkpoint state including conversation histories, and inject malicious messages into victims' threads by supplying known thread UUIDs to POST /threads/{thread_id}/runs endpoints. Thread IDs leak through frontend URLs, server logs, and observability traces, eliminating need for enumeration. Vendor-released patch (v0.9.7) confirmed by GitHub advisory GHSA-m98r-6667-4wq7. No active exploitation or POC identified at time of analysis, though detailed reproducer exists in issue #336.

ServiceAccount impersonation bypass in Rancher Fleet allows tenants with git push access to multi-tenant clusters to read secrets from any namespace across all downstream clusters. Two distinct code paths failed to properly apply RBAC constraints: Helm's lookup function executed with cluster-admin credentials instead of the impersonated ServiceAccount, and valuesFrom secret references in fleet.yaml bypassed namespace isolation. Confirmed active exploitation status unknown (not in CISA KEV). CVSS 9.9 with scope-change modifier reflects potential credential leakage to external services. Fleet versions 0.12.0 through 0.15.0 affected across multiple Rancher release branches. Patches available for all supported versions with detailed version matrix provided by SUSE.

Remote attackers can manipulate server filesystem operations in Gotenberg v8 by bypassing ExifTool metadata blocklist using group-prefix syntax (e.g., 'File:FileName' instead of 'FileName'). The vulnerability allows unauthenticated file renaming, moving, symlink/hardlink creation, and permission modification on the server. This directly bypasses the previous fix for GHSA-qmwh-9m9c-h36m. Public exploit code exists with working PoC commands. In non-containerized deployments or those with mounted volumes, attackers can achieve arbitrary file read via symlink chaining and file overwrites. CVSS 8.2 (High) with network vector, low complexity, and no authentication required.

HTTP request smuggling in Netty's netty-codec-http (HttpObjectDecoder) lets remote attackers desynchronize message boundaries by sending an HTTP/1.0 request carrying both Transfer-Encoding: chunked and Content-Length. Netty's anti-smuggling sanitization that strips the conflicting Content-Length header only runs for HTTP/1.1, so on HTTP/1.0 Netty parses the body as chunked while leaving Content-Length intact for any downstream Content-Length-first proxy, which then treats trailing chunk bytes as a new request. Publicly available exploit code exists (a working EmbeddedChannel PoC test), but EPSS is very low (0.03%, 8th percentile) and it is not in CISA KEV.

Remote unauthenticated attackers can execute arbitrary code in Snipe-IT versions 8.4.0 and earlier by uploading malicious files through the API's UploadedFilesController component. The vulnerability stems from an authorization bypass where file upload endpoints required only 'view' permission instead of 'update' permission, allowing attackers to upload and execute code without proper authentication. Fixed in commit 676a9958 (March 10, 2026). EPSS data not available. No CISA KEV listing identified at time of analysis. Public exploit code (POC) status unknown, though GitHub security advisory GHSA-xg82-2hrv-hf64 confirms the flaw.

Unauthenticated remote root access on Optoma CinemaX P2 smart projectors allows network attackers to execute arbitrary code with full system privileges. The device ships with ADB enabled on TCP 5555 without authentication (ro.adb.secure=0) and contains an unrestricted su binary, enabling complete device compromise including WiFi credential theft, malware installation, and data exfiltration. EPSS score (0.02%, 6th percentile) indicates low widespread exploitation probability, though SSVC framework assesses total technical impact. No public exploit code or active exploitation confirmed at time of analysis.

Unauthenticated remote control of the Optoma CinemaX P2 smart projector (firmware TVOS-04.24.010.04.01, Android 8.0.0) is possible through an HTTP API listening on TCP port 2345. Any host on the same network can read 74 configuration endpoints and write settings including power, volume, brightness, display mode, and network protocol toggles - notably enabling TELNET, which can widen the attack surface. No public exploit identified at time of analysis, and EPSS is very low (0.02%), but the flaw requires no credentials and CVSS is rated 9.8.

Server-side authentication bypass in the OpenTelemetry Collector Contrib azureauthextension (v0.124.0-v0.150.0) lets any holder of a valid Azure access token minted for the collector's service principal authenticate to any receiver configured with auth: azure_auth. The extension never validates bearer tokens as JWTs; it mints its own token using the client-supplied Host header as the scope and compares strings, so a token issued for an unrelated Azure resource (ARM, Graph, Key Vault, Storage) is accepted if the attacker sets a matching Host. No CISA KEV listing and EPSS is very low (0.05%), but the vendor advisory (GHSA-pjv4-3c63-699f) documents a working proof-of-concept for both replay and scope-confusion variants.

Authentication bypass in the nearform fast-jwt Node.js library (<= 6.2.3) lets unauthenticated attackers forge arbitrary, fully attacker-controlled JWTs whenever an application's asynchronous key resolver returns an empty string or zero-length buffer. fast-jwt coerces the empty key into an empty HMAC secret, auto-selects the HS256/384/512 family, and validates the token's signature against HMAC(key=''), so an attacker who signs their own token with an empty key is accepted as authentic. A working proof-of-concept is published in the vendor advisory (publicly available exploit code exists); despite the 9.1 CVSS the EPSS score is only 0.05% (17th percentile), reflecting that exploitability depends on a specific consumer coding pattern.

Authentication bypass in OpenClaw's MCP loopback interface allows local low-privilege attackers to escalate to owner-level access. Non-owner MCP client processes can spoof the 'x-openclaw-sender-is-owner' HTTP header to impersonate the owner and access owner-gated operations. Publicly available exploit code exists via GitHub commit 3cb1a56, and VulnCheck has published a detailed advisory. The vulnerability affects OpenClaw npm package versions <= 2026.4.21, with patch 2026.4.22 available since April 2026.

Shell expansion injection in OpenClaw's exec allowlist validation allows authenticated attackers to bypass command approval controls and execute arbitrary system commands. The vulnerability affects OpenClaw versions prior to 2026.4.22 through improper parsing of unquoted heredoc bodies, where shell expansion tokens ($VAR, $(), etc.) are treated as literal text during allowlist analysis but expanded at runtime. This enables attackers to embed unapproved commands within ostensibly safe allowlisted commands. VulnCheck disclosed this vulnerability, and a proof-of-concept fix commit is publicly available. CVSS 8.7 reflects high impact across confidentiality, integrity, and availability with low attack complexity.

OpenClaw before 2026.4.22 contains a time-of-check/time-of-use (TOCTOU) race condition in the OpenShell filesystem bridge that allows authenticated attackers with local access to read files outside the intended mount root by performing symlink swaps during filesystem operations. The vulnerability affects sandbox security guarantees by enabling bypass of containment restrictions through coordinated symlink manipulation, and has been confirmed patched in version 2026.4.22.

OpenClaw before 2026.4.22 contains a time-of-check/time-of-use race condition in OpenShell sandbox filesystem writes that allows authenticated attackers to redirect file writes outside the intended mount root via symlink swaps. By exploiting the window between sandbox validation and actual file write operations, an attacker with local access can manipulate symlinks to bypass sandbox filesystem restrictions and write arbitrary files to locations outside the workspace.

Authorization bypass in OpenClaw Matrix bot integration allows DM-paired attackers to execute privileged room control commands without configured permissions. Attackers who have previously established direct message pairing can exploit misaligned allowlist logic to run room control commands in bot rooms, bypassing room membership and allowlist requirements. Fixed in version 2026.4.15 after responsible disclosure by Keen Security Lab. No evidence of active exploitation; publicly available vendor advisory and fix commits reduce exploitation probability.

OpenClaw's Feishu webhook integration fails open when encryptKey is missing or callback tokens are blank, allowing remote unauthenticated attackers to bypass signature verification and replay protection mechanisms. Attackers can submit crafted webhook requests or malformed card-action callbacks directly to command dispatch without authentication, enabling arbitrary command execution. Vendor-confirmed authentication bypass; patch released in version 2026.4.15. No public exploit code or CISA KEV listing identified at time of analysis, but the fail-open behavior and network attack vector (CVSS AV:N/AC:L/PR:N) make this highly exploitable against misconfigured deployments.

Bearer token revocation bypass in OpenClaw gateway allows attackers to authenticate using rotated-out tokens until process restart. OpenClaw gateway HTTP and WebSocket handlers captured bearer authentication configuration at startup, failing to re-resolve credentials after SecretRef rotation. Attackers possessing a previously valid token can maintain unauthorized gateway access to /v1/* endpoints, /tools/invoke, plugin routes, and canvas upgrade paths even after operators rotate secrets, believing the old token is revoked. Fixed in version 2026.4.15. CVSS 9.2 reflects network-accessible attack with high complexity; no public exploit identified at time of analysis.

Arbitrary file read in OpenClaw before 2026.4.9 allows authenticated remote attackers to bypass navigation guards and access local files via browser interaction routes. Attackers exploit the ability to trigger navigation into the local Chrome DevTools Protocol (CDP) origin through act/evaluate commands, then create or read disallowed file:// URLs despite direct navigation policy restrictions. Patch available in version 2026.4.9 and confirmed included in npm release 2026.4.14. No public exploit code identified at time of analysis, CVSS 7.1 (High) with network attack vector and low complexity.

Authentication bypass in OpenClaw 2026.2.21 through 2026.4.9 allows remote unauthenticated attackers to access the sandbox noVNC helper route and gain unauthorized control of interactive browser sessions. The vulnerability exposes session credentials by failing to enforce bridge authentication on the /sandbox/novnc endpoint. OpenClaw is an open-source AI agent framework. Patch available in version 2026.4.10 and later. No evidence of active exploitation (not in CISA KEV) and EPSS data not available at time of analysis.

Complete account takeover in wger Python fitness management platform allows authenticated gym managers with no gym assignment (gym=None) to reset passwords of any other unaffiliated user and receive the new plaintext password in the HTTP response body. The vulnerability stems from a Django ORM authorization check that incorrectly evaluates None != None as False, bypassing the tenant isolation guard. Newly registered users default to gym=None state, making every public-registration wger deployment vulnerable. CVSS 9.9 Critical severity with scope change (cross-tenant impersonation). GitHub advisory GHSA-mhc8-p3jx-84mm confirms exploitation requires only low privilege (delegated gym.manage_gym permission) with no user interaction, enabling permanent victim lockout as original passwords are invalidated.

LDAP filter injection in Netflix Lemur certificate management platform allows authenticated users with valid LDAP credentials to escalate privileges to administrator by injecting metacharacters into the username field during login. Attackers manipulate group membership queries to gain unauthorized admin roles, enabling access to all certificates, private keys via /certificates/<id>/key endpoint, and CA configurations. Vendor-released patch confirmed in version 1.9.0 (GitHub advisory GHSA-3r34-vq8m-39gh). CVSS 8.1 indicates high confidentiality and integrity impact with low attack complexity from network-authenticated attackers. No public exploit code identified at time of analysis, though detailed reproduction steps exist in the advisory.

Hard-coded credentials in Vvveb's Docker deployment expose the entire application database to unauthenticated remote attackers. Versions prior to 1.0.8.2 ship with pre-configured phpMyAdmin credentials in docker-compose-apache.yaml, allowing direct database access without authentication. Attackers gain unrestricted read/write access to administrator password hashes, customer PII, and order data, enabling account takeover and data manipulation. CVSS 9.2 (Critical) reflects network-accessible attack with low complexity. Patch available in version 1.0.8.2 with vendor advisory confirmed by GitHub Security Advisory GHSA-g38h-mr9p-fjmf.

Authenticated control-panel users in Craft CMS 5.x can enumerate asset filenames and complete folder hierarchies (volume handles, UIDs, folder names, URIs) across all volumes by sending arbitrary asset IDs to the AssetsController::actionShowInFolder endpoint, bypassing volume-level viewAssets and viewPeerAssets permission checks. The flaw stems from an incomplete February 2026 patch wave that fixed four sibling endpoints but missed this method, introduced 13 days before the patch release. No public exploit identified at time of analysis; vendor-released patch fixes 5.9.18 and later. This information disclosure vulnerability enables reconnaissance for follow-up attacks against restricted asset volumes.

Unauthorized PII disclosure in Craft CMS GraphQL API allows cross-scope address enumeration via missing authorization check. A GraphQL API token scoped to any single low-privilege user group can read all addresses system-wide, including PII from restricted user groups (full names, home addresses, corporate addresses, tax IDs, GPS coordinates). The Address element resolver bypasses schema scope filtering that all other element resolvers enforce. Vendor-released patch: versions 5.9.18 and 4.17.12. Publicly available exploit code exists (detailed PoC in GitHub advisory). Affects all Craft CMS Pro deployments (v4.0.0+) using headless GraphQL APIs with user group scoping-a standard deployment pattern for Next.js/Nuxt/Gatsby frontends.

Token validation flaw in Auth0.js SDK versions 8.11.0 through 9.32.0 allows authenticated attackers to retrieve user profile information by submitting a valid access token alongside a crafted invalid ID token, bypassing access control rules defined in Auth0 Actions. The vulnerability affects applications that depend on Auth0 Actions for authorization decisions, potentially exposing sensitive user profile data to attackers holding valid but insufficiently privileged access tokens. Vendor-released patch available in version 10.0.0, discovered through coordinated disclosure by security researcher Quan Le.

Cisco IoT Field Network Director enables authenticated remote attackers with low-level privileges to crash remotely managed routers by submitting crafted requests through the web-based management interface. The vulnerability causes improper error handling that allows requesting unauthorized files from managed routers, forcing them to reload and creating a denial-of-service condition (CVSS 7.7, Changed Scope). No public exploit or active exploitation reported at time of analysis.

TCP connections through veth interfaces with XDP programs can enter a permanent deadlock state where sender and receiver sequence numbers desynchronize, causing all traffic to stall indefinitely. The vulnerability stems from improper error code handling in GSO (Generic Segmentation Offload) frame transmission when individual segments within a GSO super-frame fail - TCP interprets partial segment loss as complete frame loss, advancing receiver state without sender acknowledgment. Affects Linux kernel versions from 3.18 through 6.19.x with patches available across multiple stable branches (5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6, 7.0). EPSS score of 0.02% indicates low observed exploitation probability, and no active exploitation (KEV) or public exploit code has been identified at time of analysis.

Cross-organization ACL disclosure in Velocidex Velociraptor before 0.76.5 allows any authenticated low-privilege user to enumerate the full role and permission policy of any user in any organization by abusing the GetUserRoles gRPC endpoint with attacker-chosen Name and Org parameters. The scope-changing flaw (CVSS 3.1 7.7, S:C) breaches tenant isolation in a DFIR platform where multi-org separation is a core trust boundary. No public exploit identified at time of analysis, and EPSS is very low (0.01%), so this is a confidentiality/reconnaissance issue rather than a code-execution or actively-exploited threat.

Remote unauthenticated attackers can retrieve plaintext administrator passwords and WLAN Pre-Shared Keys from ZTE ZXHN H298A (firmware 1.1) and H108N (firmware 2.6) routers via crafted HTTP requests to the web management interface. The vulnerability enables complete network compromise through credential theft without requiring authentication. Public exploit code exists (GitHub Gist), demonstrating active researcher interest, though no CISA KEV listing indicates targeted rather than widespread exploitation. EPSS data unavailable, but the combination of network attack vector, no authentication requirement, and credential exposure presents immediate risk to affected deployments.

Authenticated users in ArcadeDB server versions prior to 26.4.2 can bypass database-scoped authorization and perform read, write, and schema mutation operations across all databases on the same server instance. Two critical implementation flaws combine: uninitialized file access maps treated as allow-all permissions, and newly-created databases via API POST /api/v1/server silently disabling their entire record-level authorization system through omitted security factory configuration. Vendor-released patch 26.4.2 addresses both defects. No public exploit identified at time of analysis, though CVSS 9.0 reflects severe authorization breakdown requiring only low-privilege authenticated access.

AVideo version 29.0 and earlier exposes API authentication secrets (APISecret) to unauthenticated remote attackers via a publicly accessible plugin configuration endpoint at objects/plugins.json.php. This vulnerability enables complete bypass of authentication controls protecting sensitive API endpoints including user enumeration (users_list) and other privileged operations. Publicly available exploit code exists (proof-of-concept demonstrated in GitHub advisory GHSA-xr49-f4rh-qcjf). Upstream fix available via commit 1c36f229 but no tagged release version has been independently confirmed at time of analysis.

Authentication bypass in Mongoose 6.x-9.x allows remote attackers to inject malicious MongoDB query operators via the $nor clause when sanitizeFilter is enabled. The vulnerability exists because Mongoose's sanitizeFilter mechanism fails to recursively sanitize the $nor logical operator, allowing injection of operators like $ne, $gt, or $regex that bypass authentication checks or extract unauthorized data. This affects only applications that explicitly enable sanitizeFilter and pass unsanitized user input directly into query methods while relying on sanitizeFilter for protection. Vendor-released patches are available for all supported release lines. No public exploit identified at time of analysis, though exploitation is straightforward for affected configurations.

Privilege escalation in Grav API Plugin (versions < 1.0.0-beta.15) allows any authenticated user with basic 'api.access' permission to elevate themselves to Super Administrator by sending a crafted PATCH request to modify their own permission configuration. The vulnerability, confirmed by vendor GitHub Security Advisory GHSA-r945-h4vm-h736, stems from inadequate authorization checks in the UsersController::update method, which permits self-editing users to overwrite the 'access' field containing role definitions. Successful exploitation grants complete CMS control including the ability to edit Twig templates outside sandbox restrictions for remote code execution. A detailed proof-of-concept is publicly available, and vendor-released patch is confirmed in version 1.0.0-beta.15.

Path traversal and authentication bypass in s3-proxy allows remote unauthenticated attackers to read, write, or delete objects in protected S3 namespaces via percent-encoded slashes (%2F) and dot-segment traversal. Three distinct bypass mechanisms exploit mismatches between encoded/decoded path handling: (1) wildcard glob patterns lacking path separators match across directory boundaries, (2) percent-encoded slashes collapse into decoded paths after authentication checks, and (3) dot-segment sequences bypass prefix-based access controls. Vendor-released patches available in commits 1320e4abd and af5ff57d. CVSS 9.4 (AV:N/AC:L/PR:N/UI:N) reflects critical network-accessible unauthenticated access, though exploitation requires specific resource path configurations using wildcards or prefix patterns.

Unauthenticated attackers can escalate privileges in OpenCTI 6.6.0-6.9.12 by impersonating any user account, including the default administrator, to query the threat intelligence platform's API without providing credentials. This authentication bypass (CWE-287) permits complete unauthorized access to cyber threat intelligence data with CVSS 9.8 critical severity. The vulnerability allows attackers to bypass all authentication controls and assume administrative privileges remotely with low attack complexity. Fixed in version 6.9.13 with workaround available via configuration change. No active exploitation (CISA KEV) or public POC confirmed at time of analysis, though EPSS data was not provided.

Server-side request forgery combined with missing authentication in firefighter-incident Python package allows unauthenticated remote attackers to exfiltrate AWS IAM credentials from cloud metadata endpoints. The `/api/v2/firefighter/raid/jira_bot` endpoint accepts arbitrary URLs in the `attachments` parameter, fetches them server-side without validation, and uploads responses as Jira attachments — enabling SSRF against internal services including `http://169.254.169.254/` (AWS EC2 Instance Metadata Service). Vendor-released patch (version 0.0.54) enforces authentication and validates attachment URLs to block private/link-local/loopback addresses. No public exploit identified at time of analysis, but exploitation is trivial given detailed advisory with exact vulnerable code paths.

Unauthenticated remote access to privileged management functions in Network-AI npm package (versions ≤5.1.2) allows attackers to read and mutate orchestrator configuration, enumerate and control agents, create or revoke security tokens, and adjust global budget ceilings. The MCP HTTP transport binds to 0.0.0.0 by default and accepts JSON-RPC tool invocation requests without authentication, session validation, or origin checks. Public exploit code exists demonstrating enumeration of 22 privileged tools and successful mutation of runtime configuration parameters via simple HTTP POST requests. Vendor-released patch: version 5.1.3 available per GitHub advisory GHSA-fj4g-2p96-q6m3.

OpenClaw's channel setup catalog lookup mechanism allowed workspace plugins to shadow bundled channel plugins and bypass trust gates during setup-time plugin loading. Low-privileged authenticated attackers on the network can craft malicious workspace plugins that execute without the intended trust verification, enabling arbitrary code execution in the OpenClaw runtime. The vulnerability was responsibly disclosed by security researchers from Keen Security Lab and patched in version 2026.4.10. No public exploit identified at time of analysis, though the fix commit reveals the exact vulnerable lookup logic attackers would target.

Authentication bypass in OpenClaw before 2026.4.9 enables untrusted workspace plugins to intercept provider authentication credentials during non-interactive onboarding. Malicious plugins can shadow legitimate provider authentication choices, causing the system to auto-enable attacker-controlled code and route sensitive API keys or credentials through untrusted handlers without user consent. Vendor-released patch available (v2026.4.9+). EPSS and KEV data not provided; exploitation requires user interaction (UI:P) and specific attack timing (AT:P), suggesting moderate real-world deployment complexity despite network attack vector.

OpenClaw npm package versions 2026.4.5 through 2026.4.9 allow privilege escalation from write-scoped operators to administrator-level configuration access. Authenticated attackers with 'operator.write' gateway credentials can modify persistent memory dreaming settings via the /dreaming endpoint, bypassing intended admin-only restrictions. Vendor-released patch available (v2026.4.10); no active exploitation confirmed at time of analysis.

Path traversal in OpenClaw's screen_record tool allows authenticated users to write files outside workspace boundaries via crafted outPath parameters, bypassing filesystem security controls. OpenClaw versions before 2026.4.10 are affected. Vendor-released patch available (version 2026.4.10 and later, including current release 2026.4.14). No active exploitation confirmed (CISA KEV negative), but publicly documented vulnerability with working proof-of-concept code in GitHub commit diff. CVSS 7.1 with high integrity impact reflects potential for unauthorized file system modifications outside intended workspace scope.

Authenticated remote attackers can bypass exec approval mechanisms in OpenClaw npm package versions 2026.2.23 through 2026.4.11 by invoking busybox or toybox multi-call binaries. The vulnerability (CWE-863: Incorrect Authorization) allows attackers to obscure which applet will execute, weakening risk classification for unsafe operations like shell command injection via 'busybox awk BEGIN{system("id")}' or 'toybox ash -c'. CVSS 8.7 (CVSS:4.0/AV:N/AC:L/PR:L) indicates network-accessible exploitation by low-privileged authenticated users. Vendor-released patch available in version 2026.4.12. EPSS and KEV data not provided; no public exploit identified at time of analysis beyond vendor-disclosed commit.

Authenticated configuration readers in OpenClaw gateway deployments can extract unredacted sensitive credentials through alias field bypass in versions prior to 2026.4.14. Attackers with legitimate config read permissions exploit sourceConfig and runtimeConfig alias fields to obtain provider API keys, gateway authentication tokens, and channel credentials that the redaction mechanism fails to sanitize. The vulnerability affects npm package 'openclaw' in gateway configurations where authenticated clients have config read access, confirmed fixed by vendor in version 2026.4.14 with patch commit 86734ef. CVSS 7.1 reflects network-accessible attack requiring low privileges with high confidentiality impact; no public exploit identified at time of analysis, though technical details published in GHSA-8372-7vhw-cm6q enable reproduction.

Remote attackers with low-privilege authentication can inject environment variable assignments into OpenClaw 2026.2.22 through 2026.4.11 to bypass shell wrapper detection mechanisms. By manipulating critical shell variables like SHELLOPTS and PS4 at the argv level, attackers achieve high-impact code execution that circumvents security controls. Vendor-released patch available in version 2026.4.12. No active exploitation confirmed (not in CISA KEV), but VulnCheck disclosed this vulnerability with specific technical details and a GitHub commit fix.

Sandbox escape in OpenClaw 2026.4.5 through 2026.4.9 allows low-privileged remote attackers to bypass sandbox boundaries and route code execution to arbitrary remote nodes by overriding exec routing parameters with host=node. This breaks sandboxed agent isolation, enabling privilege escalation and unauthorized access to production infrastructure. VulnCheck publicly disclosed this vulnerability with vendor patch available (commit dffad08). No active exploitation (CISA KEV) confirmed, but public disclosure increases exploitation risk for organizations running vulnerable OpenClaw agent deployments.

Authorization bypass in OpenClaw before 2026.4.10 allows low-privileged authenticated users with operator.write permissions to mutate persistent Matrix profile configurations that should require admin-level authority. Exploitation enables unauthorized modification of system-wide profile settings through message-tool paths, bypassing role-based access controls (CVSS:4.0 7.1 High, VI:H). Vendor patch available via GitHub commit fe0f686c. No confirmed active exploitation or public POC identified at time of analysis, with EPSS data not yet available for this 2026 CVE.

Remote code execution in Geeky Bot WordPress plugin versions ≤1.2.2 allows unauthenticated attackers to install arbitrary plugins and execute code on affected sites. The vulnerability exploits a missing authorization check in a nopriv AJAX handler that permits attacker-controlled function dispatch to a plugin installer, enabling download and extraction of malicious ZIP files directly into wp-content/plugins/. With CVSS 9.8 (critical), network-exploitable without authentication, and EPSS data unavailable, this represents a severe risk to all WordPress sites running vulnerable versions until patched.

Authentication bypass in MoreConvert Pro for WordPress allows remote unauthenticated attackers to hijack any user account, including administrators, by exploiting token reuse in the guest waitlist verification flow. Attackers obtain a verification token for their own email, change the guest customer email to the target victim's email via the public waitlist API, then use the original token to authenticate as the victim. This critical vulnerability (CVSS 9.8) affects all versions through 1.9.14, with network-accessible, low-complexity exploitation requiring no privileges or user interaction. EPSS data not available; no confirmed active exploitation or public POC identified at time of analysis.

Password reset bypass in Gambio GX4 e-commerce platform allows remote unauthenticated attackers to set arbitrary passwords for any user account when the account ID is known, leading to complete account takeover. Affects versions 4.0.0.0 through 4.9.2.0, patched in February 2024 security update (2024-02 v1.0.0). SSVC framework rates this as automatable with total technical impact despite EPSS score of 0.02%, indicating high severity for targeted attacks against Gambio installations. No active exploitation confirmed via CISA KEV, but authentication bypass primitives are frequently weaponized in e-commerce platforms.

Authenticated attackers can escalate privileges to administrator in Pelican Web User Interface versions 7.21 through 7.24 by manipulating database records before legitimate admin users log in. This vulnerability was discovered by a Claude coding agent on April 2, 2026, and affects servers with Server.UIAdminUsers or Server.AdminGroups configured where designated admins have not previously authenticated. No public exploit code exists, and Pelican Command Line reports no confirmed exploitation in OSDF-managed services. Vendor patches are available across all affected minor release series (>=v7.21.5, >=v7.22.3, >=v7.23.3, >=v7.24.2), with fix commit 7f73b9c3e677 addressing CWE-863 (Incorrect Authorization).

Unauthenticated remote attackers can trigger complete database wipes and data deletion in phpVMS 7.x through 7.0.5 by accessing an exposed legacy importer endpoint at /importer. The vulnerability stems from deprecated import functionality that remained publicly accessible without authentication checks, allowing remote data modification or destruction. Vendor-released patch (v7.0.6) confirmed via GitHub advisory GHSA-fv26-4939-62fh. No CISA KEV listing or public exploit code identified at time of analysis, but trivial exploitation (CVSS AV:N/AC:L/PR:N/UI:N) makes active targeting likely.

Server-Side Template Injection (SSTI) in Thymeleaf 3.1.4.RELEASE and earlier allows remote attackers to execute arbitrary code via specially crafted expressions that bypass the template engine's sandbox restrictions. Applications passing unsanitized user input to sandboxed template contexts are vulnerable to full server compromise. Vendor-released patch is available in version 3.1.5.RELEASE. The CVSS 9.0 CRITICAL rating reflects the potential for remote code execution with high confidentiality, integrity, and availability impact, though the AC:H (high attack complexity) indicates exploitation requires specific application patterns where user input flows directly into sandboxed template contexts without validation.

Credential brute-forcing in Signal K Server versions ≤2.24.0 allows remote unauthenticated attackers to bypass HTTP login rate limiting by sending unlimited password guesses through the WebSocket authentication endpoint at approximately 20 attempts per second. The HTTP login endpoints are protected by express-rate-limit (default: 100 attempts per 10-minute window), but the WebSocket path processes login requests without any throttling, enabling dictionary attacks to complete in minutes. Publicly available exploit code exists demonstrating the bypass technique. Signal K servers are commonly deployed on boat networks where they may be accessible to other devices on the same LAN, increasing exposure risk.

Argo Workflows v3 (< 3.7.14) and v4 (< 4.0.5) allow users to bypass templateReferencing Strict/Secure mode restrictions by setting WorkflowSpec fields like hostNetwork, serviceAccountName, securityContext, tolerations, and volumes. The incomplete fix for CVE-2026-31892 only blocked podSpecPatch but left other security-sensitive fields unvalidated. Authenticated users with create Workflow permission can inject host network access, switch service accounts, modify pod security contexts, or schedule on control-plane nodes despite referencing hardened WorkflowTemplates. Vendor-released patch: v3.7.14 and v4.0.5 (commit 2727f3f). No public exploit identified at time of analysis, but exploitation is straightforward given detailed reproduction steps in the advisory.

Unauthenticated bootstrap takeover in nginx-ui 2.3.5 allows remote attackers to hijack the initial installation process via crafted POST requests to /api/install endpoint. An attacker who successfully exploits the installation window gains full administrative control over the nginx-ui instance before legitimate administrators complete setup. No vendor-released patch identified at time of analysis, creating extended exposure risk for newly deployed instances.

Unauthenticated attackers can hijack the administrator account during nginx-ui's first-run installation window by claiming the /api/install endpoint before legitimate operators. This race-condition vulnerability in nginx-ui versions 2.0.0 through 2.3.7 bypasses authentication controls entirely, allowing complete instance takeover with attacker-controlled credentials. The request-encryption mechanism protects only transit confidentiality, not authorization. Attack complexity is rated HIGH due to the narrow time window between deployment and legitimate setup completion. EPSS data unavailable; no CISA KEV listing or public POC identified at time of analysis, but exploitation requires only standard HTTP tools and timing.

Missing authorization checks in Argo Workflows v4.0.0-4.0.4 allow any authenticated user-even those with fake Bearer tokens-to create, read, update, and delete Kubernetes ConfigMaps containing workflow synchronization limits. The ConfigMap-backed sync provider (server/sync/sync_cm.go) completely omits auth.CanI permission validation on all four CRUD endpoints. Publicly available exploit code exists (detailed PoC in advisory). CVSS 8.5 reflects network-accessible authentication bypass enabling high integrity/availability impact through denial-of-service and arbitrary ConfigMap manipulation. Patch released in version 4.0.5 adding checkConfigMapPermission() calls to validate Kubernetes RBAC before operations.

Missing authorization in Kirby CMS allows authenticated Panel users to access sensitive site configuration, user data, and role information regardless of configured permission restrictions. Authenticated attackers with low-privilege Panel accounts can enumerate all users, access the site model, and view role configurations including permission settings-even when site administrators explicitly disabled these capabilities via wildcard permission denial ('*': false). Vendor-released patches in versions 4.9.0 and 5.4.0 add missing permission gates for site.access, user.access/users.access, user.list/users.list, and role information. No public exploit identified at time of analysis, but exploitation requires only authenticated Panel access with network connectivity.

Unauthenticated attackers can enumerate and exfiltrate all customer order records from Easy PayPal Events & Tickets plugin for WordPress through an exposed QR code scanning endpoint. The scan_qr.php file accepts sequential WordPress post IDs without authentication, enabling complete database harvesting of payment and customer information. Publicly available exploit code exists, but no evidence of active exploitation (not in CISA KEV). The plugin was officially closed and removed from WordPress.org on 2026-03-18, leaving existing installations vulnerable with no official patch path.

Hardcoded authentication bypass in Easy PayPal Events & Tickets plugin allows unauthenticated remote attackers to retrieve sensitive order data by supplying 'test' as the hash parameter to the QR code scanning endpoint. Attackers can access PayPal transaction IDs, customer emails, purchase amounts, and ticket information for any order by enumerating post IDs. Public exploit code exists on GitHub, significantly lowering the exploitation barrier. The plugin was officially closed by WordPress.org on 2026-03-18, leaving installations vulnerable with no future patches.

Authorization bypass in Quarkus allows remote unauthenticated attackers to access protected HTTP endpoints by appending semicolons (matrix parameters) to request URLs. Quarkus version 3.32.4 and multiple other branches are affected due to a path-normalization inconsistency between the security layer (which checks raw paths preserving matrix parameters) and RESTEasy Reactive routing (which strips them). Attackers can send requests like '/api/admin;anything' to bypass policies protecting '/api/admin' while still routing to the protected endpoint. Vendor-released patches available across four version branches (3.20.6.1, 3.27.3.1, 3.33.1.1, 3.35.1.1). No public exploit identified at time of analysis, but the attack technique is straightforward given the detailed GitHub Security Lab advisory (GHSA-rc95-pcm8-65v9).

Remote code execution in Arelle webserver (versions prior to 2.39.10) allows unauthenticated attackers to execute arbitrary Python code by submitting malicious plugin URLs to the /rest/configure endpoint. The vulnerability stems from the webserver's plugin manager accepting and executing external Python files without authentication or URL validation. A patch is available in version 2.39.10 (GitHub PR #2320). CVSS 9.8 with network vector, no privileges required, and EPSS data not provided. No CISA KEV listing or confirmed active exploitation at time of analysis.

Wildcard injection in Apache Polaris table names allows authenticated users to escalate privileges and access unauthorized S3 data across tables. By creating tables with literal asterisk characters (e.g., 'f*.t1', '*.*'), attackers bypass IAM policy scoping and obtain temporary S3 credentials that match other tables' storage paths. Confirmed exploitation scenarios include reading Iceberg metadata control files, listing table prefixes, and creating/deleting objects in victim tables' S3 locations - even when the attacker lacks direct Polaris permissions on those tables. Private testing confirmed this on both MinIO and AWS S3 against Polaris 1.4.0. The CVSS 9.4 (Critical) reflects network-accessible exploitation requiring only low privileges (namespace-scoped TABLE_CREATE), with high confidentiality, integrity, and availability impact across system and subsequent components. No public exploit code or CISA KEV listing identified at time of analysis, but the Apache advisory provides detailed attack mechanics.

Buffer overflow in Qualcomm Snapdragon firmware enables authentication bypass on adjacent networks, allowing remote unauthenticated attackers to achieve complete system compromise with high impact to confidentiality, integrity, and availability. The vulnerability stems from incorrect authorization logic (CWE-863) that fails to prevent buffer overflow conditions. CVSS score of 9.6 reflects adjacent network attack vector with low complexity and no required privileges or user interaction, with scope change indicating container/hypervisor escape or lateral movement potential. No CISA KEV listing or public exploit identified at time of analysis, though EPSS data not available to assess exploitation probability.

Apache Polaris issues overly-permissive temporary storage credentials during staged table creation, allowing authenticated attackers to redirect vended credentials to attacker-controlled storage locations. The vulnerability stems from missing validation and overlap checks before credential issuance - attackers supply a custom 'location' parameter or 'write.data.path'/'write.metadata.path' properties that become effective immediately without verification. This enables unauthorized access to arbitrary storage resources beyond intended table boundaries, with CVSS 9.4 severity indicating high impact across confidentiality, integrity, and availability of both vulnerable and subsequent systems.

Authenticated attackers with table configuration privileges can bypass storage location validation in Apache Polaris by manipulating the write.metadata.path property during ALTER TABLE operations. This forces Polaris to write metadata files to attacker-controlled storage locations without proper validation, then subsequently issue cloud storage credentials for those locations. The vulnerability enables unauthorized access to and potential corruption of data belonging to other tables within the catalog's allowedLocations scope, particularly when polaris.config.allow.unstructured.table.location=true. EPSS data not available; no public exploit identified at time of analysis.

Hardcoded telnet backdoor in D-Link DIR-456U Hardware Revision A1 firmware grants remote unauthenticated attackers root shell access using static credentials ('Alphanetworks' / 'whdrv01_dlob_dir456U'). The telnet daemon launches automatically at boot via /etc/init0.d/S80telnetd.sh and validates credentials through strcmp() comparison against hardcoded values in /etc/config/image_sign. Device is End-of-Life with no patches forthcoming. CVSS 9.8 reflects network-accessible unauthenticated remote code execution, though exploitation requires local network access to telnet service.
