Authentication Bypass
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
How It Works
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications. Instead of cracking passwords through brute force, attackers manipulate the authentication process itself to gain unauthorized entry. This typically occurs through one of several pathways: exploiting hardcoded credentials embedded in source code or configuration files, manipulating parameters in authentication requests to skip verification steps, or leveraging broken session management that fails to properly validate user identity.
The attack flow often begins with reconnaissance to identify authentication endpoints and their underlying logic. Attackers may probe for default administrative credentials that were never changed, test whether certain URL paths bypass login requirements entirely, or intercept and modify authentication tokens to escalate privileges. In multi-step authentication processes, flaws in state management can allow attackers to complete only partial verification steps while still gaining full access.
More sophisticated variants exploit single sign-on (SSO) or OAuth implementations where misconfigurations in trust relationships allow attackers to forge authentication assertions. Parameter tampering—such as changing a "role=user" field to "role=admin" in a request—can trick poorly designed systems into granting elevated access without proper verification.
Impact
- Complete account takeover — attackers gain full control of user accounts, including administrative accounts, without knowing legitimate credentials
- Unauthorized data access — ability to view, modify, or exfiltrate sensitive information including customer data, financial records, and intellectual property
- System-wide compromise — admin-level access enables installation of backdoors, modification of security controls, and complete infrastructure takeover
- Lateral movement — bypassed authentication provides a foothold for moving deeper into networks and accessing additional systems
- Compliance violations — unauthorized access triggers breach notification requirements and regulatory penalties
Real-World Examples
CrushFTP suffered a critical authentication bypass allowing attackers to access file-sharing functionality without any credentials. The vulnerability enabled direct server-side template injection, leading to remote code execution on affected systems. Attackers actively exploited this in the wild to establish persistent access to enterprise file servers.
Palo Alto's Expedition migration tool contained a flaw permitting attackers to reset administrative credentials without authentication. This allowed complete takeover of the migration environment, potentially exposing network configurations and security policies being transferred between systems.
SolarWinds Web Help Desk (CVE-2024-28987) shipped with hardcoded internal credentials that could not be changed through normal administrative functions. Attackers discovering these credentials gained full administrative access to helpdesk systems containing sensitive organizational information and user data.
Mitigation
- Implement multi-factor authentication (MFA) — requires attackers to compromise additional verification factors beyond bypassed primary authentication
- Eliminate hardcoded credentials — use secure credential management systems and rotate all default credentials during deployment
- Enforce authentication on all endpoints — verify every request requires valid authentication; no "hidden" administrative paths should exist
- Implement proper session management — use cryptographically secure session tokens, validate on server-side, enforce timeout policies
- Apply principle of least privilege — limit damage by ensuring even authenticated users only access necessary resources
- Regular security testing — conduct penetration testing specifically targeting authentication logic and flows
Recent CVEs (37440)
Privilege-boundary bypass in OpenClaw's Discord guild-action handling (versions 2026.6.6 up to but not including 2026.6.9) lets a low-privilege authenticated caller invoke operations that should require stronger authorization. By abusing misconfigured input paths, the attacker skips the cross-provider requester authorization step and executes restricted guild operations. No public exploit identified at time of analysis; the CVSS 4.0 score of 7.2 reflects high integrity and availability impact with no confidentiality exposure.
Privilege escalation via authorization bypass in OpenClaw 2026.6.6 through 2026.6.8 allows a low-privileged, authenticated caller to invoke message-mutation operations that should require stronger authorization, letting them execute privileged actions. The flaw is a missing authorization check (CWE-862) on mutation input paths and requires the affected feature to be enabled and reachable. No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Authorization bypass in OpenClaw before 2026.6.9 lets a lower-trust caller escape the exec-approval trust boundary through the flock wrapper, executing or persisting privileged actions the caller was never authorized to perform. The CVSS 4.0 vector (PR:L) indicates an authenticated but low-privilege actor can achieve high confidentiality, integrity, and availability impact when the affected feature is enabled. Reported by VulnCheck with a vendor GitHub Security Advisory (GHSA-3fp5-v549-9v66); no public exploit identified at time of analysis and it is not listed in CISA KEV.
Authorization bypass via symlink following in OpenClaw's mirror sync feature (versions before 2026.6.9) lets a lower-privilege caller escalate into actions that should require stronger authorization. By planting or referencing symlink parents on a remote mirror target, an authenticated attacker can trick the sync logic into resolving links that cross policy and trust boundaries, yielding high confidentiality and integrity impact. There is no public exploit identified at time of analysis and no CISA KEV listing; no EPSS score was supplied.
Privilege escalation via broken authorization in the OpenClaw @openclaw/feishu integration (versions 2026.6.6 and earlier) allows a lower-trust, already-authenticated caller to invoke Feishu permission tools that should have been blocked by per-account disablement settings. Because the enforcement gap lets a low-privilege actor perform actions requiring stronger authorization, the flaw carries high confidentiality and integrity impact (CVSS 4.0 base 8.6). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Authorization bypass in the @openclaw/feishu npm package (versions <= 2026.6.6) allows a lower-trust caller - or attacker-influenced input reaching a configured input path - to perform Feishu (Lark) actions that should have required stronger authorization, because per-account disablement can be ignored. Authenticated remote attackers can trigger unauthorized operations affecting confidentiality and integrity; no public exploit has been identified at time of analysis, and the flaw is fixed in version 2026.6.9. Real-world impact is gated by the operator's configuration and whether untrusted input can reach the affected feature.
Privilege escalation in OpenClaw before 2026.6.8 lets a lower-trust, already-authenticated caller invoke admin-restricted operations by abusing OpenAI-compatible HTTP model-override input paths, bypassing the authorization checks that should gate those actions. The flaw was reported by VulnCheck and stems from missing authorization (CWE-862) on override-driven request handling. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
Unauthenticated CRUD on the provider-management API in 9Router (through 0.4.41) lets remote attackers with no credentials enumerate, create, modify, and delete provider connections via the Next.js routes under src/app/api/providers/*. Because the /api/providers endpoints ship without authentication middleware, attackers can harvest partial credentials, OAuth tokens, and API keys, redirect AI traffic to attacker-controlled providers, or wipe all connections for a full denial of service; the companion /api/usage/stats endpoint further leaks full plaintext API keys. Rated CVSS 4.0 9.3 (critical); no public exploit identified at time of analysis, though the trivial access makes exploitation straightforward.
Insecure Direct Object Reference in ChurchCRM before 7.4.0 lets an authenticated non-admin user with EditSelf access read and modify other congregations' family records by supplying a different family's familyId to family-scoped endpoints. Because the backend loads the family entity by the attacker-controlled ID without ownership verification, a user who also holds the Notes permission can additionally create notes on unrelated families' records, breaking the intended self-service scope. No public exploit identified at time of analysis, though the flaw is trivially reproducible by manipulating a request parameter.
Access key authentication bypass in Apollo ConfigService (com.ctrip.framework.apollo, versions < 2.5.2) lets an unauthenticated remote attacker read raw configuration data even when AccessKey/management-key authentication is enabled. The service mis-parses the appId on the /configfiles/raw/{appId}/{clusterName}/{namespace} endpoint as the literal string 'raw', so no matching secret is found and the signature check is skipped for the real target app. No public exploit identified at time of analysis; the flaw is fixed in Apollo 2.5.2.
Authentication bypass in Apollo (Ctrip apolloconfig) ConfigService allows an unauthenticated remote attacker to read protected configuration data from /configs and /configfiles endpoints even when AccessKey/management-key authentication is enabled. The flaw stems from ConfigService accepting a non-canonical appId variant (e.g. accented or trailing-space forms) that misses the AccessKey secret cache lookup - causing signature verification to be skipped - while the downstream release lookup still resolves the value to the real, protected app under equivalence-treating database collations. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the confidentiality-only impact drives the CVSS 7.5 (High) rating.
Cross-tenant authentication bypass in Decidim (the Ruby-on-Rails participatory-democracy platform) lets a JWT issued in one organization (tenant) be replayed against a second organization's GraphQL API by simply changing the HTTP Host header. An authenticated Org 1 principal (admin or API user) can then read Org 2's admin-only participantDetails field, harvest Org 2 participant personal data, and reach Org 2's proposal.answer mutation path. Rated CVSS 8.5 with a scope change; the vendor advisory publishes step-by-step reproduction, but no CISA KEV listing and no EPSS score were provided, so widespread active exploitation is not established.
Remote code execution in ThemisNETPanel (vendor 4real) allows unauthenticated network attackers to fully compromise the underlying server by abusing a file-upload endpoint that lacks any authentication check. An attacker submits a base64-encoded PHP payload, writes it as an arbitrary PHP file, and executes it in the web application's context. Reported by CERT-PL with a CVSS 4.0 base score of 9.3; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Cross-tenant privilege escalation in the repository creation functionality shared by Google Cloud BigQuery, Dataform, and Colab Enterprise allowed an authenticated GCP user to take over repositories belonging to other tenants. Rated CVSS 4.0 9.4 (critical) with a scope-changing cross-tenant impact, the flaw was a Missing Authorization (CWE-862) issue affecting the managed services between October 2025 and 10 May 2026. Google reports no public exploit identified at time of analysis; the defect was fixed server-side on 10 May 2026 with no customer action required.
Bluetooth authentication bypass in the Evbee DC-80 DC EV charging station lets an attacker within radio range issue privileged commands without any credentials, enabling sensitive information disclosure, forced reboots, and - most dangerously - the ability to push an arbitrary firmware update URL to the device. Reported by DIVD (DIVD-2026-00001), it carries CVSS 4.0 base 8.7 (High). No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Missing authentication on the evbee DC-80 EV charging station exposes an administrative web server on TCP port 8090 that requires no login, allowing remote unauthenticated attackers to read sensitive data such as configured passwords and to upload arbitrary files via multiple endpoints. Reported through the DIVD CSIRT coordinated-disclosure program (DIVD-2026-00001), the flaw carries a CVSS 4.0 base score of 9.3 with a fully network-exploitable, no-privilege vector. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Authentication bypass in the WorkScout Core WordPress plugin (versions up to and including 1.7.08) can be triggered through a Cross-Site Request Forgery flaw, letting an off-site attacker perform privileged authentication-related actions in the context of a logged-in victim who visits a malicious page. The issue was reported by Patchstack and carries a CVSS 8.8; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Because exploitation hinges on tricking an authenticated user into clicking (UI:R), it is high-impact but not point-and-click automatable.
Broken access control in the AcyMailing SMTP Newsletter plugin for WordPress (versions up to and including 10.11.1) lets an authenticated low-privileged user reach functionality that should be restricted, impacting integrity and, most notably, availability of the plugin's newsletter/mailing operations. The flaw is a missing authorization check (CWE-862) reported by Patchstack; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Note an inconsistency in the source data: the CVE description states affected 'through <= 10.11.1' while the linked Patchstack advisory slug references 10.10.2 - the exact patched version is not confirmed from the input.
Broken access control in the UX-Themes Flatsome WordPress theme (versions up to and including 3.20.5) allows remote unauthenticated attackers to reach functionality or data that should be authorization-gated, resulting in confidentiality-only impact per the CVSS vector. The flaw stems from a missing authorization check (CWE-862) and was catalogued by Patchstack, but there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Flatsome is one of the most widely sold commercial WooCommerce themes, so the affected footprint is substantial even though only information disclosure (not integrity or availability) is implicated.
Broken access control in the Themeum Kirki WordPress customizer framework (versions up to and including 6.0.13) allows remote unauthenticated attackers to reach functionality protected by incorrectly configured access-control levels, resulting in disclosure of sensitive information. The flaw was reported by Patchstack and stems from a missing authorization check (CWE-862); no public exploit has been identified at time of analysis. With a CVSS of 7.5 driven purely by confidentiality impact, the practical risk is unauthorized data exposure rather than site takeover.
Broken access control in the Event Tickets WordPress plugin (versions up to and including 5.28.5) lets remote unauthenticated attackers modify data they should not be able to reach because an authorization check is missing on a privileged action. The flaw carries a 7.5 CVSS with an integrity-only impact (I:H) and no confidentiality or availability effect, and there is no public exploit identified at time of analysis. It was disclosed by Patchstack and affects default installations of the plugin.
Authentication bypass in the Metagauss ProfileGrid WordPress plugin (versions up to and including 5.9.9.6) lets remote unauthenticated attackers abuse the password recovery flow as an alternate channel to hijack arbitrary user accounts, including administrators. Because the flaw is exploitable over the network with no privileges and no user interaction (CVSS 7.5, I:H), it enables full account takeover on affected WordPress sites. No public exploit is identified at time of analysis and it is not in CISA KEV, but the low attack complexity makes it an attractive target once details circulate.
Broken access control in the ThemeHunk Open Shop WordPress theme (versions up to and including 1.7.1) lets an authenticated low-privileged user reach functionality that should be restricted, tampering with data and degrading site availability. Reported by Patchstack and rated CVSS 7.1, the flaw stems from missing authorization checks on a privileged action. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Broken access control in the Phil Kurth "Advanced Forms" WordPress plugin (all versions up to and including 1.9.3.7) lets remote unauthenticated attackers reach a form-handling function that fails to verify authorization, enabling unauthorized modification of form data or settings. The CVSS 3.1 score is 7.5 with integrity-only impact and no confidentiality or availability loss. Reported by Patchstack; no public exploit identified at time of analysis and not listed in CISA KEV.
Arbitrary file deletion in JoomShaper's Helix Ultimate template framework for Joomla allows unauthenticated remote attackers to delete files on the server due to a missing authorization check (CWE-862). Any anonymous user can reach the vulnerable functionality without credentials (PR:N/UI:N), enabling deletion of critical Joomla files to corrupt or take down the site. No public exploit has been identified at time of analysis, and the CVE is not listed in CISA KEV.
Insecure direct object reference (IDOR) in Dassault Systèmes Tuleap Enterprise Edition 17.0 through 17.5 lets attackers read other users' data by manipulating a user-controlled key/identifier, breaking horizontal authorization boundaries. The CVSS 3.1 vector (AV:N/PR:N) scores it as remotely reachable with high confidentiality impact but no integrity or availability effect. No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Access-control bypass in EIPStackGroup OpENer 2.3.0 (commit 76b95cf) lets any unauthenticated network attacker hijack another client's EtherNet/IP encapsulation session by replaying a valid session_handle, because the stack validates the handle against a global session list but never binds it to the originating TCP socket. Affected industrial devices running this open-source stack can have their EtherNet/IP command channel abused for read/write operations under another client's authority. No CISA KEV listing exists, but a researcher gist referenced in the advisory appears to publish exploit details, and the CVSS 9.1 rating reflects high confidentiality and integrity impact.
Privilege elevation in Microsoft Edge (Chromium-based) lets a network attacker escalate privileges by luring a victim into loading crafted web content that triggers an untrusted pointer dereference (CWE-822). Microsoft rates it CVSS 8.3, driven by a scope change (sandbox/boundary crossing) and full confidentiality, integrity, and availability impact, but exploitation requires user interaction and is of high attack complexity. No public exploit identified at time of analysis (E:U), it is not on CISA KEV, and an official vendor fix is available.
Cross-organization account disruption in Capgo before 12.128.2 lets an enterprise administrator in one organization destroy the email/password login of users belonging to different organizations. By abusing the SSO prelink-users endpoint, an attacker holding the org.update_settings permission with an active SSO provider can permanently remove password identities for any user whose email matches the provider's domain, locking victims out of native authentication and forcing them onto the attacker's SSO or a password-reset recovery flow. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the flaw was reported by VulnCheck.
Account takeover in Capgo before 12.128.2 arises because the email-change endpoint performs no current-password re-authentication and no verification of the existing email address, letting an attacker who already holds a valid session cookie or an authenticated browser silently repoint the account email. By seizing the recovery address, the attacker captures password-reset flows and sidesteps multi-factor authentication, converting a hijacked session into durable full account control. There is no public exploit identified at time of analysis, but the flaw is vendor-confirmed via GitHub Security Advisory GHSA-9px4-w25f-mvm4 and reported by VulnCheck.
Authentication bypass in Flowise 3.0.13 and earlier lets remote unauthenticated attackers forge valid JWTs and impersonate any user, including administrators, because the enterprise passport authentication middleware silently falls back to publicly known hardcoded secrets ('auth_token', 'refresh_token') and default audience/issuer values ('AUDIENCE', 'ISSUER') whenever the JWT_AUTH_TOKEN_SECRET, JWT_REFRESH_TOKEN_SECRET, JWT_AUDIENCE, and JWT_ISSUER environment variables are unset. Reported by VulnCheck and rated CVSS 4.0 9.3 (Critical), it grants full account takeover, though there is no public exploit identified at time of analysis and no CISA KEV listing.
Credential exfiltration in Crawl4AI's Docker API server (all versions before 0.8.8) lets remote unauthenticated attackers steal secrets from the host. By abusing the exposed /md, /llm, and /llm/job endpoints, an attacker supplies a malicious base_url to redirect outbound LLM API calls and sets api_token to the special form env:VARIABLE_NAME, causing the server to resolve and leak arbitrary environment variables - including provider API keys and the JWT SECRET_KEY, which in turn enables full authentication bypass. No public exploit identified at time of analysis, but the flaw is trivially exploitable and reported by VulnCheck with an assigned CVSS 4.0 score of 8.8.
Privilege escalation in Capgo before 12.128.2 lets demoted super_admin users retain organization-wide bundle management rights because the org_users.user_right column is not cleared when their role binding is deleted. A user who once held super_admin can continue invoking the delete_non_compliant_bundles and count_non_compliant_bundles RPCs to enumerate and bulk-delete non-compliant bundles across the entire organization indefinitely, well after their privileges were supposedly revoked. Reported by VulnCheck; no public exploit identified at time of analysis and not listed in CISA KEV.
Broken authorization in PraisonAI Platform (praisonai-platform) before 0.1.9 lets any low-privileged workspace member modify owner- or admin-created projects, issues, and agents because the PATCH routes only check for workspace-member role instead of owner/admin. Because a member can reassign a project's lead_id to their own user id, they can then satisfy and bypass the delete route's owner/admin check to destroy owner-created projects. No public exploit identified at time of analysis, though the flaw is trivially reachable by any authenticated tenant member.
System prompt extraction and unauthorized tool invocation in PraisonAI before 4.6.78 arise because the prompt-injection defense ships with its blocking threshold defaulting to CRITICAL, so HIGH-severity injection attempts are detected and logged but never blocked. Any remote user interacting with a PraisonAI agent can submit single-vector prompt injection (instruction overrides, financial manipulation) that scores HIGH and passes through, leaking the system prompt and triggering agent tools without authorization. No public exploit identified at time of analysis, and the issue is not in CISA KEV; the vendor CVSS 4.0 score is 8.7 (High).
Privilege escalation in the Genolve AI image and video generation plugin for WordPress (all versions through 5.0.5) lets authenticated users with Contributor-level access or above update arbitrary WordPress options because the genolve_setOpt() function performs no capability check. By enabling the users_can_register option and setting default_role to administrator, a low-privileged user can register a new administrator account and fully take over the site. Reported by Wordfence with a CVSS of 8.8; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Privilege escalation in the Simple JWT Login WordPress plugin (all versions through 3.6.6) lets an authenticated subscriber-level user forge an Administrator session by injecting arbitrary identity claims into the JWT payload. Because AuthenticateService::generatePayload() only overwrites payload keys that appear in the admin-configured jwt_payload allowlist, attacker-supplied claims such as email, id, or username survive and are signed with the site's HS256 secret; the token is then redeemed at /autologin to log in as any administrator. Reported by Wordfence with no public exploit identified at time of analysis and no CISA KEV listing.
Authentication bypass in the Hydro-Québec Le Circuit Électrique EV charging station backend lets remote unauthenticated attackers open connections directly to the charging-station WebSocket endpoint, which lacks proper access control (CWE-284), and leverage that access for privilege escalation. All backend versions prior to the June 2026 fix are affected, and the CVSS 4.0 base score of 9.3 (critical) reflects full compromise of confidentiality, integrity, and availability over the network with no privileges or user interaction. Reported through CISA ICS-CERT (ICSA-26-188-01); no public exploit identified at time of analysis and it is not listed in CISA KEV.
Authentication bypass in the Drupal Commerce Guest Registration contributed module allows remote unauthenticated attackers to circumvent identity verification during the guest checkout/registration flow, per Drupal advisory SA-CONTRIB-2026-079. The CVSS 9.1 scoring (C:H/I:H) indicates an attacker can gain unauthorized access to or hijack account/order data without credentials or user interaction. No public exploit has been identified at time of analysis, and the low EPSS score (0.24%, 15th percentile) suggests exploitation is not yet widespread.
Missing authorization in the Drupal LocalGov Workflows contrib module (all versions 0.0.0 through 1.6.0, fixed in 1.6.0) lets remote attackers reach protected workflow-related routes through forceful browsing without proper permission checks. The flaw carries a vendor CVSS of 9.8 (AV:N/AC:L/PR:N/UI:N), but EPSS is low (0.14%, 4th percentile) and there is no public exploit identified at time of analysis. Affected sites are Drupal deployments running this LocalGov Drupal editorial-workflow module.
Broken access control in the Frappe framework (all versions prior to 16.19.0) lets a low-privileged authenticated user modify public Workspaces they should not control, because the update_page endpoint failed to enforce the Workspace Manager edit permission on public workspaces. Any user able to reach the endpoint can alter shared workspace layout and content, an integrity-only impact with no data disclosure. No public exploit has been identified, EPSS/KEV data were not provided, and the fix is shipped in Frappe 16.19.0.
Authentication replay in Misskey before 2026.6.0 lets an attacker reuse a valid TOTP code that should be single-use, because UserAuthService fails to invalidate a code after its first successful use within the same time step. An adversary who concurrently captures a victim's password and one TOTP value can replay that code to authenticate, enabling unauthorized actions up to account takeover. No public exploit has been identified at time of analysis and it is not listed in CISA KEV; the vendor fixed the flaw in release 2026.6.0.
Local memory-corruption escalation in Imagination Technologies' Graphics DDK (the PowerVR GPU driver stack) lets an unprivileged user trigger a use-after-free by issuing an improper sequence of GPU system calls. By forcing a failure path in the MMU mapping logic, an attacker leaves internal driver state incompletely cleaned up, enabling unauthorized read/write access to physical memory from shader code. There is no public exploit identified at time of analysis and EPSS is low (0.15%), but the flaw carries high confidentiality, integrity, and availability impact for local attackers.
Cross-tenant information disclosure in OpenReplay's self-hosted session-replay backend (versions 1.22.0 through 1.26.x) lets any authenticated low-privilege user retrieve the first 15 seconds of another tenant's DOM session-replay recording. The getFirstMob endpoint issued a 15-second presigned S3 URL keyed only on a user-supplied session path, while validateProjectAccess confirmed project-to-tenant ownership but never confirmed that the requested session actually belonged to that project, breaking multi-tenant isolation. No public exploit identified at time of analysis, but the flaw is trivially triggerable by any valid account and is fixed in 1.27.0.
Broken object-level authorization (IDOR) in OpenReplay 1.27.0 and earlier lets any authenticated project member tamper with other users' private data: the notes.delete, dashboards.update_widget, and dashboards.remove_widget backend functions omit the ownership predicate their sibling read/edit functions enforce, so they act on any note or widget matching only an id and project/dashboard id. An authenticated low-privilege member can delete another user's private session notes and remove or rewrite widgets on another user's private dashboards. There is no public exploit identified and no CISA KEV listing; impact is integrity/availability of other tenants' data, not disclosure (CVSS 7.1, C:N/I:H/A:L).
Authentication bypass in the miniOrange OAuth Single Sign On - SSO (OAuth Client) WordPress plugin (versions up to and including 38.5.8) lets remote unauthenticated attackers abuse an alternate authentication path in the password-recovery flow to log in as arbitrary users, including administrators. Rated CVSS 9.8, the flaw grants full account takeover without credentials or user interaction; there is no public exploit identified at time of analysis, but the plugin's SSO role and low attack complexity make it a high-value target.
Authentication bypass in the miniOrange Social Login and Register (Discord, Google, Twitter, LinkedIn) WordPress plugin through version 7.7.0 lets unauthenticated attackers seize any account, including administrators. The Profile Completion flow trusts an attacker-supplied 'email_field' POST value without confirming it matches the OAuth provider's verified identity, and the send_otp_token() routine leaks a SHA-512(customer_key||otp) hash to the client where the OTP is one of only 99,000 values and customer_key is a static (often empty) option - so the OTP can be brute-forced offline in under a second. Rated CVSS 9.8; no public exploit identified at time of analysis, but the full attack primitive is described in the Wordfence advisory.
Authorization bypass in RabbitMQ topic permissions lets an authenticated user with restricted topic rights publish to or bind on topics they should be denied, but only during metadata-store failure windows. When the Khepri metadata store returns a lookup error, the topic-permission result collapses to 'undefined', which the internal authorization backend fails open and treats as 'allow'. There is no public exploit identified at time of analysis and it is not on CISA KEV; the CVSS 4.0 base score is 7.0.
Improper authorization in RabbitMQ broker (versions prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6) allows an authenticated client to create foreign bindings against another connection's volatile amq.rabbitmq.reply-to (direct reply-to) destination, so persistent route entries survive after unbind and can leak RPC reply traffic intended for other clients. The flaw stems from Khepri-backed deletion checks that omit these volatile pseudo-queues, letting stale routes persist. No public exploit identified at time of analysis; exploitation requires valid credentials and has high attack complexity per the vendor CVSS 4.0 vector.
Authentication bypass in RabbitMQ (broker versions prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6) lets a loopback-restricted account such as the default guest user authenticate from a remote network when the broker sits behind a trusted PROXY-protocol path and the backend listener is loopback-bound. Because the loopback check evaluates the listener-side socket address (which appears as 127.0.0.1 to the local proxy) instead of the real client source carried in the PROXY header, the 'local only' restriction on guest is silently defeated across AMQP 0-9-1, AMQP 1.0, and the Stream Protocol. SSVC records a proof-of-concept; there is no CISA KEV listing and EPSS is low (0.34%, 26th percentile), indicating the flaw is potent but not yet mass-exploited.
Privilege escalation within RustDesk before 1.4.9 lets an authenticated peer that was granted only a limited session type (FileTransfer, PortForward, ViewCamera, or Terminal) send control messages and login options reserved for a full Remote session, because the server never re-validates a session's authorized scope. The result is that a peer given, for example, file-transfer-only access can observe and control the host's screen and input as if it held full remote-control rights. No public exploit has been identified at time of analysis, though the fixing pull request and commit are public, and no EPSS or CISA KEV data was supplied.
Authentication step-up bypass in Logto self-hosted auth infrastructure prior to 1.41.0 lets an already-authenticated user manage MFA factors without re-proving their identity. The Account Center accepted any of the user's own verified records - including a self-created WebAuthn passkey-registration record - as proof of identity verification, so an attacker holding only a valid Account API bearer token could forge the logto-verification-id header and satisfy step-up checks. No public exploit identified at time of analysis, and it is not listed in CISA KEV; the flaw is fixed in 1.41.0.
Broken authorization in Snipe-IT before 8.6.2 lets an authenticated non-admin user who holds users.view and users.edit - but explicitly not users.delete - soft-delete other non-admin user accounts by POSTing delete_user=1 to /users/bulksave. The root cause is that BulkUsersController::destroy() checks only the 'update' authorization, so the delete permission gate is never enforced. No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Authorization bypass in Teracity TeraMIS (versions V03.26.01.14 through the 30.04.2026 build) lets an authenticated low-privilege user tamper with a user-controlled object key to reach records and functions belonging to other users or higher-privilege roles (CWE-639 IDOR). The CVSS vector (AV:N/AC:L/PR:L/UI:N) confirms remote, low-complexity exploitation by any account holder, yielding high confidentiality and integrity impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; EPSS and POC data were not provided.
Argument injection in Flux159 MCP Server Kubernetes before 3.9.0 lets remote attackers redirect kubectl operations to an attacker-controlled API server by smuggling a leading-dash `--server` flag through the resourceType and name parameters of the kubectl_get, kubectl_describe, and kubectl_delete structured tools. Because the injected values bypass the assertNoDangerousFlags check, the operator's bearer token is transmitted to the external server, enabling full Kubernetes cluster compromise. Reported by VulnCheck, it carries CVSS 4.0 9.3, has publicly available exploit code, and a vendor patch in release 3.9.0; there is no confirmed active exploitation.
Authorization bypass in Snipe-IT allows authenticated low-privileged users to move maintenance records to assets outside their company scope by manipulating the asset_id field during PATCH/PUT requests on /api/v1/maintenances/{id}. The vulnerability affects versions before 8.6.2 and is fixed in that release. EPSS remains low (0.22%) with no known active exploitation or public proof-of-concept.
Broken object-level authorization in Krayin CRM (Laravel CRM) through version 2.2.3 lets any authenticated user tamper with leads, persons, organizations, quotes, and activities belonging to other users. Because the edit, update, and destroy methods across five controllers never verify record ownership, a low-privileged account can read, modify, reassign, or delete arbitrary CRM records by manipulating the object ID. Publicly available exploit details exist (reported by VulnCheck), though the issue is not listed in CISA KEV and no EPSS score was provided.
Cross-tenant account takeover in Prowler (cloud security platform) before 5.30.3 lets an authenticated attacker who operates a controlled SAML IdP obtain a tenant-scoped JWT for a victim tenant. The ACS finish logic in api/src/backend/api/v1/views.py derived the destination tenant from the user-asserted email domain rather than binding token issuance to the validated SAML configuration, so an attacker completing a legitimate SAML flow for their own domain while asserting a victim-domain email address receives a SAMLToken and JWT for the wrong tenant. Rated CVSS 9.6 (scope-changing); no public exploit identified at time of analysis and it is not listed in CISA KEV.
Privilege escalation in ZITADEL identity platform (before 4.15.3) allows an attacker holding a low-privilege OAuth2 token to exchange it for elevated permissions at a different application, because the token-exchange endpoint fails to bind the subject token to the requesting client and does not constrain requested scopes to the original token's scopes. Any authenticated principal with a valid low-scope token can escalate laterally across relying applications; no public exploit is identified at time of analysis and it is not listed in CISA KEV. A vendor patch (4.15.3) and fixing commit are available.
Privilege escalation in Adam Retail Automation's MobilMen 20T (versions v3 through build 10072026) lets an authenticated low-privileged user manipulate a user-controlled key (CWE-639) to access resources or actions belonging to other, higher-privileged accounts. The flaw carries CVSS 8.8 and was reported by Turkey's national CERT (TR-CERT), but no public exploit identified at time of analysis and it is not in CISA KEV. The vendor was contacted but did not respond, so no coordinated fix is confirmed.
Missing authorization in the Squirrly SEO plugin for WordPress (all versions through 14.0.0) lets unauthenticated attackers create arbitrary posts by abusing a leaked API token, and — when the Advanced Custom Fields (ACF) plugin is also active — plant stored cross-site scripting that fires whenever any user views the injected page. Wordfence rates it CVSS 7.2 with scope change because a single unauthenticated request can seed persistent content and script that later executes in visitors' and administrators' browsers. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the unauthenticated, low-complexity nature makes it an attractive target for automated WordPress campaigns.
Authorization bypass in Simple Machines Forum (SMF) 2.1 before 2.1.8 and 3.0 before 3.0 Alpha 5 lets any authenticated low-privileged member manipulate the attachment moderation queue without the required approve_posts permission. A single-character operator mistake in Sources/Actions/AttachmentApprove.php makes the permission check evaluate to true for everyone, so an ordinary user can approve, reject, or delete pending attachments on any board and enumerate other users' unapproved uploads. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; the flaw was reported by VulnCheck and a vendor patch is available.
Authentication bypass in 9Router (decolua/9router) versions prior to 0.5.2 lets remote unauthenticated attackers reach protected /v1/* proxy APIs because src/dashboardGuard.js trusts any request arriving over loopback. When 9Router runs behind a same-host reverse proxy that forwards public traffic through 127.0.0.1 - the standard production deployment - external requests are misclassified as local, exposing /v1/models and enabling abuse of configured upstream AI provider credentials. No public exploit identified at time of analysis; scored CVSS 8.3 with a scope change reflecting downstream provider-credential abuse.
Authorization-gate bypass in 9Router (decolua/9router) before 0.5.2 lets a remote unauthenticated attacker reach protected upstream LLM functionality through the /codex/* path, which next.config.mjs rewrites to /api/v1/responses without ever passing through the dashboardGuard API-key check. Because src/dashboardGuard.js only allowlists /v1, /v1beta, /api/v1, and /api/v1beta — omitting /codex — attackers can force the server to make upstream provider calls billed to operator-stored LLM credentials. No public exploit identified at time of analysis; fixed in 0.5.2.
Authentication bypass in 9Router (decolua/9router) before 0.5.2 lets a remote unauthenticated attacker forge a 'Host: localhost' header so the /v1 LLM proxy treats the request as local and skips API-key checks. Once past authentication, an attacker abuses stored provider credentials for upstream LLM calls and leverages /v1/search's searxng provider_options.baseUrl to force server-side requests to internal or cloud-metadata endpoints (SSRF). No public exploit identified at time of analysis, though the fixing commit is public, and EPSS/KEV signals are not provided.
Improper permission enforcement in JetBrains TeamCity before 2026.1.2 lets authenticated low-privilege users modify CI/CD pipelines they should not control, undermining build integrity and potentially exposing pipeline secrets. Reported by JetBrains itself and carrying a CVSS 8.1, the flaw is a missing-authorization issue (CWE-862) rather than a memory-safety bug. No public exploit identified at time of analysis, and it is not listed in CISA KEV.
Missing authentication on the ST Engineering iDirect iQ200 satellite terminal exposes the /api/identity and /api/ REST endpoints to any unauthenticated party on the network, letting them harvest the serial number, Device ID (DID), Terminal Private Key identifier (TPK), MAC address, and firmware version. Because the DID and TPK underpin satellite-network authentication on the iDirect platform, the leaked identifiers can support terminal impersonation and targeted reconnaissance. Reported by CISA ICS-CERT (ICSA-26-183-01); no public exploit identified at time of analysis, and no EPSS score was provided.
Broken authorization in PraisonAI Platform before 0.1.9 lets an authenticated workspace member delete owner-created issue dependencies they should not be able to remove. The DELETE dependency route accepts either endpoint of a dependency edge and validates delete permission only against the caller-supplied issue URL, so a member blocked (403) via the owner's issue endpoint can delete the same edge by targeting their own member-owned issue endpoint. Reported by VulnCheck with a vendor patch available; no public exploit identified at time of analysis and it is not on CISA KEV.
Instance-wide data breach in Vikunja before 2.2.1 lets remote attackers exfiltrate and destroy every file attachment across all projects on a server. Two flaws chain together: the LinkSharing.ReadAll endpoint leaks share hashes to any user with read access, enabling escalation to admin-level shares, and the GetTaskAttachment endpoint validates permissions against a user-supplied task ID while fetching the attachment by an unrelated sequential ID, an insecure-direct-object-reference that ignores ownership. Rated CVSS 4.0 9.3 (critical) with a network, unauthenticated vector; no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Improper access control in Capgo before 12.128.2 lets holders of write-scoped API keys directly mutate protected channel configuration fields (such as public, allow_emulator, and security-related flags) through the PostgREST data layer, bypassing intended application route restrictions. The flaw stems from a null authentication check in the database immutability trigger, allowing a low-privileged but authenticated actor to alter integrity-sensitive delivery settings for a Capacitor live-update backend. Reported by VulnCheck; no public exploit identified at time of analysis and not listed in CISA KEV.
Account takeover in Capgo before 12.128.2 stems from a password-change endpoint that omits current-password validation (CWE-620), letting an attacker who holds any temporary or low-privilege session set a new password without proving they know the old one. Because the CVSS 4.0 vector reflects a low-privilege (PR:L) network attacker with high confidentiality and integrity impact, a hijacked or briefly-borrowed session can be converted into permanent control, locking legitimate users out. No public exploit identified at time of analysis and the flaw is not on CISA KEV, so risk is credible but not confirmed as actively exploited.
Information disclosure in Capgo before 12.128.2 lets unauthenticated remote attackers call the get_orgs_v7(userid) RPC endpoint with arbitrary user UUIDs to read foreign users' organization memberships, roles, management emails, and billing metadata. The endpoint remained publicly invokable despite intended private access controls, so any internet-facing Capgo deployment on an affected version exposes tenant data cross-account. No public exploit has been identified at time of analysis, though the trivial invocation pattern (supply a UUID) makes weaponization straightforward.
Authorization bypass in FlaskBB through 2.2.0 lets authenticated moderators perform lock, unlock, delete, or hide actions on topics in forums they have no authority over. By anchoring a crafted batch request with a low-ID topic from a permitted forum, the attacker slips past a permission check that is applied only to the first result. No public exploit is identified at time of analysis, and the flaw is fixed in commit acc88cf.
SQL injection in Dell PowerFlex Manager prior to version 5.1.0.1 allows a remote, low-privileged authenticated attacker to inject crafted SQL commands through the management interface, resulting in information disclosure and unauthorized access to data beyond the attacker's authorized scope. Rated CVSS 8.5 with a scope-changed vector, the flaw is reported by Dell (DSA-2026-066) and carries confidentiality impact; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Broken object-level authorization in R-SOFT DMS lets any authenticated user download arbitrary files by manipulating the object ID in multiple file-download endpoints, since the application enforces only session authentication and never checks whether the requester owns or may access the requested file. This is an authenticated confidentiality breach (CVSS 4.0 7.1) affecting all versions prior to v3.19-2862 and v3.17-2580. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Server-Side Request Forgery in the guardrails-detectors component allows a remote attacker to submit a crafted XML Schema Definition (XSD) that forces the service to make attacker-directed requests, reaching cloud metadata services, the Kubernetes API, internal MinIO object storage, and other internal endpoints, and to read local files such as service account tokens and pod secrets. Because the flaw is blind SSRF chained to local file disclosure inside a container/Kubernetes context, an attacker can harvest credentials and pivot deeper into the cluster. No public exploit identified at time of analysis, but the CVSS 9.3 rating and scope-changing impact make this high priority for affected AI-guardrails deployments.
Authorization bypass in Apache IoTDB's REST API endpoint /rest/v2/fastLastQuery allows authenticated users to access last-value time-series data they are not authorized to view. Affected versions span the 1.3.x branch (1.3.5 through 1.3.7) and the 2.0.x branch (2.0.5 through 2.0.9). No public exploit code or active exploitation has been identified at time of analysis, but the REST interface nature of the flaw means any valid credential holder can attempt unauthorized data retrieval without elevated privilege.
Unauthenticated denial of service in Apache IoTDB (1.0.0 through 2.0.9) allows remote attackers to crash or degrade the DataNode process when the AirGap pipe receiver is enabled. The receiver's readLength method reads an attacker-controlled 32-bit length field from a raw TCP connection on port 9780 and passes it directly to new byte[length], letting a single connection trigger a heap allocation of up to ~2 GB and exhaust JVM memory. No public exploit has been identified at time of analysis, but exploitation is trivial once the feature is enabled, and Apache has released a fixed version (2.0.10).
Authentication bypass via capture-replay in Apache IoTDB (1.0.0 through 2.0.9) lets attackers reuse stale credentials against the REST interface because Basic Authentication continues to accept cached credentials that should have been invalidated. An attacker who has captured or previously held valid credentials can keep authenticating after those credentials should have expired or been revoked, gaining full read/write control of the time-series database. No public exploit identified at time of analysis, and EPSS is low (0.18%, 8th percentile), so no active exploitation is indicated despite the 9.8 CVSS.
Privilege escalation in the WP Business Intelligence Lite WordPress plugin (all versions through 3.2.0) allows authenticated Subscriber-level users to tamper with stored SQL queries because the plugin fails to enforce a capability/authorization check on the query-modification action (CWE-862). When an administrator later views the maliciously altered query, the attacker's arbitrary SQL executes in the admin context, enabling account takeover or full site compromise. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV; it was reported through the Wordfence threat intelligence program.
Sensitive information exposure in the Chat Help WordPress plugin versions ≤ 3.1.3 allows unauthenticated attackers to extract customer lead data and WordPress credentials via unprotected REST API endpoints. Attackers can retrieve names, emails, phone numbers, geolocation, and full user account details. No active exploitation or public exploit is known at this time; the vulnerability has a CVSS 7.5 base score but a low EPSS probability (0.47%).
Authentication bypass in the LoginPress Pro WordPress plugin (versions ≤ 6.2.3) lets unauthenticated attackers log in as any existing user - including Administrators - when the Spotify Social Login addon is enabled. The flaw stems from the plugin trusting the unverified email returned by Spotify's /v1/me endpoint to match and authenticate a WordPress account, so an attacker who registers a Spotify account with a victim's email gains that victim's session. No public exploit has been identified at time of analysis; CVSS is 8.1 with attack complexity rated High due to the required addon configuration.
Authentication bypass in the LoginPress Pro WordPress plugin (versions up to and including 6.2.3) lets unauthenticated attackers hijack any existing account, including administrators, by abusing the GitHub OAuth social-login callback. The loginpress_on_github_login() function binds the login session to profile[0]['email'] from GitHub's /user/emails endpoint without checking the verified flag, so an attacker who adds an unverified email matching a victim's account and triggers the callback can be logged in as that user. This maps to CWE-287 and carries a CVSS 8.1; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Authentication bypass in the LoginPress Pro WordPress plugin (versions ≤ 6.2.3) lets unauthenticated attackers hijack any existing account - administrators included - by exploiting the Discord OAuth login handler, which trusts the email returned by Discord without checking Discord's verified flag. An attacker who knows a target's WordPress email registers a Discord account with that same (unverified) email and completes the normal OAuth flow to receive an authenticated session as the victim. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the flaw was reported by Wordfence and is a full account-takeover primitive.
Authentication bypass in Hermes WebUI before 0.51.307 lets unauthenticated remote attackers reach onboarding endpoints that are supposed to be restricted to loopback traffic by spoofing an X-Forwarded-For header with a 127.0.0.1 value. Once past the origin check, an attacker can pivot to server-side request forgery against internal services and cloud metadata endpoints, overwrite LLM provider configuration and API keys, or start an OAuth device-code flow to mint persistent tokens saved in auth.json. A vendor patch exists; the flaw carries a CVSS 4.0 score of 9.3, but no public exploit code has been identified at time of analysis.
Broken authorization in Pimcore's Studio API lets a standard editor-level user create class definitions without administrative rights, because the POST /pimcore-studio/api/class/definition/configuration-view/detail/create endpoint checks the 'objects' permission rather than the 'classes' permission. Because class-definition creation writes new database tables and PHP class files to the server, this permission gap grants low-privileged users significant control over the application's data model and codebase, and absent API-layer UID validation malformed UIDs reach model-layer validation and surface internal exceptions. No public exploit identified at time of analysis; the flaw is fixed in 2025.4.6 and 2026.1.6.
Full admin account takeover in Pimcore (Studio backend) before 2025.4.6 and 2026.1.6 lets an unauthenticated attacker who knows a valid admin username hijack that account by submitting a password-reset request with an attacker-controlled resetPasswordUrl; the server appends a genuine recovery token to that URL and emails it to the victim, so a single victim click leaks the token to the attacker, who authenticates via POST /pimcore-studio/api/login/token with full admin rights and bypasses 2FA. GitHub advisory GHSA-h854-c3m3-mh5v classifies this as an authentication bypass (CWE-640). No public exploit identified at time of analysis, and it is not listed in CISA KEV; EPSS was not provided.
Arbitrary file disclosure in docuForm GmbH Client v11.11c allows a remote, low-privileged attacker to read sensitive server files through the dfm-menu_report.php component by supplying attacker-controlled path input. The NVD description asserts arbitrary code execution and the vendor gist tags it 'RCE'/'Authentication Bypass', but the concrete described capability is reading configuration files, source code, and system files, with code execution unsubstantiated in the available data. No public exploit is confirmed via a flag, though a third-party gist reference (ZeroBreach-GmbH) is published and likely carries proof-of-concept detail; EPSS is low at 0.35% (27th percentile) and the CVE is not on CISA KEV.
Authenticated remote code execution in docuForm GmbH Client v11.11c lets low-privileged users abuse the report.php file-upload component to run arbitrary code on the server. The flaw combines an authorization-bypass weakness (CWE-639) with unrestricted file upload, so an attacker with any valid account can escalate to full server compromise. No public exploit identified at time of analysis, though a third-party gist referenced in NVD may contain technical write-up material; EPSS is low (0.24%, 15th percentile) and the CVE is not in CISA KEV.
Broken object-level authorization in docuForm GmbH Client v11.11c lets an authenticated remote user manipulate the user settings component to read and modify other users' account data, with the reporter additionally claiming this can escalate to arbitrary code execution. The flaw stems from user-controlled object references (CWE-639) that the application fails to authorize against the requesting session. There is no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV; EPSS is low at 0.27% (18th percentile).
