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 (31268)
Missing Authorization vulnerability in BeRocket Advanced AJAX Product Filters allows Exploiting Incorrectly Configured Access Control Security Levels.6.3.3. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Incorrect authorization checks in GitLab CE/EE expose confidential issue details to authenticated low-privileged users under specific conditions. The flaw spans an enormous version range starting from 12.0, meaning a large population of self-hosted GitLab instances running unpatched versions is potentially affected. A publicly available exploit was disclosed via HackerOne (report #3578216), which elevates practical risk above what the low CVSS score of 3.1 alone suggests, even though active exploitation has not been confirmed by CISA KEV.
Incorrect authorization enforcement in GitLab CE/EE exposes hidden merge requests to unauthorized modification by authenticated users holding developer-role permissions. The flaw spans a wide version range - from 15.10 through the patched releases 18.10.8, 18.11.5, and 19.0.2 - meaning a large proportion of self-managed GitLab deployments are potentially affected. A publicly available proof-of-concept exists via a disclosed HackerOne report, raising the practical exploitation risk beyond what the medium CVSS score alone suggests; no confirmed active exploitation (CISA KEV) has been recorded at time of analysis.
Incorrect authorization enforcement in GitLab Enterprise Edition allows an authenticated user holding the Security Manager role to manage project security configurations even when the relevant security feature has been administratively disabled. Affecting all EE versions from 13.9 through the patched releases (18.10.8, 18.11.5, 19.0.2), the flaw bypasses the feature-disabled gate by failing to validate feature state alongside role-based permissions. No public exploit is confirmed as actively exploited (not in CISA KEV), though a publicly available HackerOne exploit report exists, and EPSS data was not provided in available intelligence.
Account takeover in GitLab Enterprise Edition versions 15.5 through 19.0.2 allows an authenticated group Owner to hijack other group members' accounts through improper authorization in the Group SAML identity management functionality. Publicly available exploit code exists via a HackerOne report, and GitLab released patched versions 18.10.8, 18.11.5, and 19.0.2 on 2026-06-10. The flaw stems from CWE-639 (Authorization Bypass Through User-Controlled Key) and yields a scope-changing high-impact compromise per CVSS 3.1.
Merge request diff manipulation in GitLab CE/EE allows authenticated users with developer-role permissions to hide file changes from code reviewers by exploiting improper input handling of file names, undermining the integrity of the code review process. Publicly available exploit code exists via HackerOne report #3638136 (tagged 'exploit' in vendor references), though no confirmed active exploitation has been recorded in CISA KEV. The vulnerability spans a broad version range from 15.9 through the patched releases, meaning self-managed GitLab deployments without current patch levels are at risk from malicious insiders or compromised developer accounts bypassing review gates.
Privilege escalation in Google Cloud Dialogflow CX allows authenticated users holding specific IAM roles to abuse the playbook import functionality and potentially take over the entire GCP project. Google has confirmed the issue was patched server-side on 15 March 2026 with no customer action required, and no public exploit has been identified at time of analysis.
Missing Authorization vulnerability in TemplateHouse Soledad allows Accessing Functionality Not Properly Constrained by ACLs.2.5. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Unauthorized record modification in Cerebrate before 1.37 allows any authenticated user to overwrite arbitrary records of the same entity type by injecting a foreign primary key into CRUD edit requests. The flaw stems from permissive mass-assignment defaults across several entity types - User, Role, UserSetting, LocalTool, PermissionLimitation, and EnumerationCollection - where the ORM's patchEntity() accepted attacker-controlled id values from request bodies, redirecting the SQL UPDATE to an unrelated row. Because the UserSettings edit endpoint was reachable by all authenticated users, the most accessible exploitation path required only valid session credentials. No public exploit code or CISA KEV listing has been identified at time of analysis, though the integrity impact on Role and User entities carries privilege-escalation potential that elevates real-world severity above the base CVSS score alone.
Authentication bypass via primary weakness (CWE-305) in ABB Freelance DCS affects every major release line from 2013 through 2024, allowing a locally authenticated low-privilege user to circumvent the product's authentication mechanism and gain elevated control over the system. The CVSS vector (AV:L/PR:L/I:H) confirms the attacker must already hold a foothold on the host but can then achieve high integrity impact - particularly serious in an industrial control system context where manipulating controller configurations can affect physical processes. No public exploit code and no CISA KEV listing have been identified at time of analysis, though the wide version span and OT deployment context elevate remediation urgency.
Mass-assignment in Cerebrate before v1.37 lets remote attackers reaching a generic CRUD add endpoint supply a client-controlled id when creating objects, because the add() handler stripped id from the raw $params but not from the normalized $input passed to entity patching. No public exploit identified at time of analysis, but the upstream commit aff1ca7 makes the root cause and exploit path trivially recoverable. CVSS 4.0 of 8.7 (VI:H) reflects integrity-only impact on the vulnerable system.
Authorization bypass through User-Controlled key vulnerability in Essential Plugin WP Logo Showcase Responsive Slider and Carousel allows Exploiting Incorrectly Configured Access Control Security. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Remote code execution in UpdraftPlus: WP Backup & Migration Plugin for WordPress (versions ≤1.26.4) allows unauthenticated attackers to forge RPC commands as the connected administrator by bypassing signature verification in the UpdraftPlus_Remote_Communications_V2::wp_loaded handler. A flaw in how unchecked decryption return values are handled collapses the encryption key to an all-zero value, enabling arbitrary plugin upload and activation. No public exploit identified at time of analysis, but the plugin's massive WordPress install base and trivial post-bypass impact make this a high-priority patch.
Authorization bypass in Spring for GraphQL (versions 1.0.0-1.0.6, 1.3.0-1.3.8, 1.4.0-1.4.5, and 2.0.0-2.0.3) allows remote attackers to invoke @Controller data fetcher methods whose security annotations are declared on parent classes or interfaces, because the framework's annotation detection does not consistently resolve annotations across type hierarchies. The flaw is rated CVSS 7.5 (confidentiality-only impact) and no public exploit identified at time of analysis, but the network-reachable, no-privilege CVSS vector makes any affected GraphQL endpoint a meaningful exposure.
X509AuthenticationProvider in Spring Web Services issues fully authenticated tokens from client certificates without enforcing Spring Security's account lifecycle checks, meaning disabled, locked, expired, or credentials-expired accounts can successfully authenticate. This affects all maintained release branches from 3.1.0 through 5.0.1 and was reported by VMware, the Spring project maintainer. No public exploit or CISA KEV listing has been identified at time of analysis, but the bypass is meaningful in environments that rely on account-disablement as the primary deprovisioning control rather than certificate revocation.
Remote takeover of Oracle PeopleSoft Enterprise PeopleTools 8.61 and 8.62 is possible through the Updates Environment Management component via unauthenticated HTTP requests. The CVSS 9.8 vector (AV:N/AC:L/PR:N/UI:N) indicates trivial network-based exploitation against any internet- or intranet-exposed instance, with full confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, but Oracle's 'easily exploitable' language and the unauthenticated nature make this a high-priority patching target.
Page-cache corruption in FreeBSD's kTLS-RX subsystem (CVE-2026-45257 / FreeBSD-SA-26:26.kTLS) enables an unprivileged local user to overwrite arbitrary bytes in the backing physical page of any world-readable file, including SUID-root binaries, by exploiting in-place AES-GCM decryption running directly over sendfile(2)-produced EXTPG mbufs via the kernel direct map (DMAP). The write bypasses the VFS layer entirely, defeating file permissions, mount options, and chflags schg immutable flags - making this the FreeBSD functional equivalent of Linux CVE-2022-0847 (Dirty Pipe). A public exploit (bumsrakete.c) is included in the oss-security disclosure and achieves reliable root LPE in approximately 1.5 seconds on default FreeBSD 13.0 through 15.0 on amd64, arm64, and riscv; no public KEV listing has been identified at time of analysis.
Privilege escalation in Palo Alto Networks PAN-OS on PA-Series and VM-Series firewalls and Panorama appliances allows an authenticated CLI administrator to perform operations at the root OS level, bypassing intended privilege boundaries through a missing authorization control (CWE-862). The risk is substantially gated by the requirement for existing administrative CLI access (CVSS PR:H), making insider threats and compromised admin credentials the primary real-world attack paths. No public exploits or confirmed active exploitation have been identified at time of analysis, and the vendor's own E:U supplemental metric reinforces the low exploitation urgency - though root-level OS access to a firewall represents a severe impact if the prerequisite is met.
Security control bypass in Palo Alto Networks Prisma Access Agent for Linux enables a local, low-privileged attacker to route network traffic outside the VPN tunnel, undermining the core data-in-transit protection the agent is designed to enforce. Only Linux deployments are affected - Windows, macOS, iOS, Android, and ChromeOS are explicitly not impacted. No public exploit code exists at time of analysis and this vulnerability is not listed in the CISA KEV catalog, but the CVSS 4.0 confidentiality impact is rated High due to the exposure of unencrypted traffic to untrusted network paths.
Broken authorization in the Copy & Delete Posts WordPress plugin through 1.5.4 lets any authenticated user assigned a plugin-enabled (non-admin) role invoke every operation exposed by the cdp_action_handling AJAX endpoint, enabling post deletion and plugin-setting tampering. The flaw stems from a missing per-function capability check that the dispatcher should enforce based on the f parameter. No public exploit identified at time of analysis and the CVE is not on CISA KEV.
A person with access to a Mac may be able to bypass Login Window. Rated low severity (CVSS 3.5), this vulnerability is no authentication required, low attack complexity. This Improper Authentication vulnerability could allow attackers to bypass authentication mechanisms to gain unauthorized access.
Authorization bypass in Sharp (code16/sharp Laravel CMS package) versions 9.0.0 through 9.22.3 permits authenticated users lacking create permissions to invoke Quick Creation Command endpoints directly, circumventing the authorization layer to either retrieve entity creation forms or submit new records. The root cause is a missing `authorizationManager->check('create', $entityKey)` call in both the constructor and the `create` method of `ApiEntityListQuickCreationCommandController`, meaning the restriction enforced at the entity list level was not replicated at the command controller level. No public exploit exists and no CISA KEV listing is present; vendor-released patch v9.22.3 closes both vulnerable endpoints.
Message spoofing and app state corruption in Baileys WhatsApp library (versions < 6.7.22 and < 7.0.0-rc12) allow remote attackers to forge messages.upsert events, inject history sync data, and jam the app state sync system by sending crafted protocolMessage payloads via placeholderResendMessage. The flaw stems from missing self-origin checks on protocol message types that should only originate from the user's own device. No public exploit identified at time of analysis, but the upstream patch and detailed advisory provide enough information for exploit reconstruction.
Host validation bypass in Litestar's AllowedHostsMiddleware allows unauthenticated remote attackers to circumvent the allowed-hosts allowlist by omitting the HTTP Host header and substituting a client-controlled X-Forwarded-Host header set to any whitelisted domain. Affected are all Litestar deployments (pip/litestar < 2.22.0) using AllowedHostsConfig that are reachable without a trusted reverse proxy stripping X-Forwarded-Host - a condition reflected in the CVSS AC:H rating. Publicly available exploit code exists demonstrating the bypass; no CISA KEV listing at time of analysis.
Input validation bypass in Fission (Kubernetes-native serverless framework) prior to version 1.25.0 allows authenticated users with Kubernetes API access to create HTTPTrigger resources with malformed or unsafe URL paths, achieving low-integrity routing manipulation. The RelativeURL and Prefix fields in HTTPTriggerSpec were validated only at the Fission CLI layer; when the post-CRD-modernization admission webhook was retired in favor of API-server CEL, no CEL rules were authored for those two fields - leaving a complete gap exploitable via kubectl apply or direct Kubernetes REST API calls. No public exploit code exists and this CVE is not listed in CISA KEV, but the bypass is straightforward for any cluster user with HTTPTrigger create rights.
Cross-namespace access control bypass in Fission (Kubernetes-native serverless framework) prior to 1.24.0 allows an authenticated tenant with permission to create Function objects in their own namespace to reference an Environment in a different namespace, because the admission webhook in pkg/webhook/function.go validated namespace equality only for secrets and configmaps, not for spec.environment.namespace. An attacker can pivot across Kubernetes namespace boundaries and pull in environment configuration belonging to other tenants (CVSS 8.5, scope-changed, high confidentiality impact). No public exploit identified at time of analysis, though the upstream fix and full patch diff are publicly available on GitHub.
Cross-namespace access control bypass in Fission prior to 1.24.0 allows an authenticated tenant to reference Package objects belonging to other Kubernetes namespaces because the admission webhook validated namespaces for Secret and ConfigMap references but omitted the equivalent check for PackageRef.Namespace. A low-privileged user with rights to create Function objects in their own namespace can therefore reach Package contents in arbitrary namespaces, producing a scope-changing confidentiality breach (CVSS 7.7, S:C, C:H). No public exploit identified at time of analysis; not listed in CISA KEV.
Cross-namespace information disclosure in Fission prior to 1.24.0 allows a low-privilege developer with namespace-scoped permissions to create a KubernetesWatchTrigger (KWT) that establishes a persistent watch channel against Kubernetes resources in any other namespace, breaking the platform's tenancy boundary. The flaw stems from missing namespace-equality enforcement in the kubewatcher controller, which honored an attacker-supplied Spec.Namespace value and even treated an empty value as cluster-wide visibility. No public exploit identified at time of analysis, but the upstream fix (PR #3379, merged into v1.24.0) and detailed advisory GHSA-gc3j-79f2-7vvw confirm the defect class.
Unauthenticated arbitrary file write in Splunk Enterprise (below 10.2.4 and 10.0.7) and Splunk Cloud Platform (below 10.4.2604.3 and 10.2.2510.14) allows remote attackers to create or truncate files on the host via an unauthenticated PostgreSQL sidecar service endpoint. The CVSS 9.8 vector (AV:N/AC:L/PR:N/UI:N) reflects trivial network exploitation, and no public exploit identified at time of analysis, though the missing-auth root cause and Splunk's high-value position in enterprise SOCs makes prompt patching warranted.
Improper access control on the saved search ownership reassignment endpoint in Splunk Enterprise and Splunk Cloud Platform allows a highly privileged authenticated user - one whose role contains the `edit_saved_search_owner` capability - to reassign saved search ownership to users outside their authorized scope. Affected versions span Splunk Enterprise below 10.2.4 and 10.0.7, and multiple Splunk Cloud Platform branches below their respective fixed builds. No public exploit has been identified at time of analysis, and the PR:H CVSS requirement confines risk primarily to insider threats or scenarios involving compromised privileged Splunk accounts.
Classic dashboard drill-down links in Splunk Enterprise and Splunk Cloud Platform can be weaponized by low-privileged authenticated users to silently redirect victims to attacker-controlled external sites, enabling data exfiltration. The flaw stems from an incomplete URL scheme validator that recognizes only 'http://' and 'https://' prefixes, allowing protocol-relative URLs like '//attacker.com' to bypass the external-navigation warning dialog entirely. No public exploit code exists and no active exploitation is confirmed (not in CISA KEV), but the attack requires only a low-privileged account and a single victim click, making it a realistic phishing vector in multi-tenant or large enterprise Splunk deployments.
Artifact pin decay in vLLM (< 0.22.0) allows pinned model deployments to silently load secondary artifacts - dynamic code modules, GGUF files, image processors, retrieval side weights, and same-repository subfolder configs - from unpinned or default HuggingFace Hub revisions, undermining supply-chain integrity guarantees. Operators who supply `--revision` or `--code-revision` to audit and lock a specific model version can unknowingly serve behavior-affecting components that fall outside the reviewed artifact set. No public exploit code has been identified at time of analysis, but seven discrete affected code paths across vllm's model loader and registry subsystems have been confirmed at commit 3795d7acf431980e62e738493f437ae2a51549da, with a fix released in vLLM 0.22.0 via PR #42616.
Privilege escalation in Apache OFBiz versions prior to 24.09.07 allows a low-privileged authenticated user to elevate their permissions to a higher-privileged role, leading to full compromise of confidentiality, integrity, and availability of the ERP system. The flaw is rooted in improper authorization (CWE-285) and is exploitable remotely over the network with low complexity once valid low-tier credentials are held. No public exploit identified at time of analysis, and EPSS scoring (0.02%) plus CISA SSVC (Exploitation: none) suggest no observed exploitation activity yet.
Cross-workspace authorization bypass in Plane (makeplane) prior to version 1.3.1 allows any authenticated user of one workspace to read, copy, delete, and overwrite file assets belonging to other workspaces on the same instance. The flaw stems from missing membership checks on V2 asset endpoints and is fixed in v1.3.1; no public exploit identified at time of analysis.
Authentication bypass in Roxy-WI versions 8.2.6.4 and prior allows remote unauthenticated attackers to reach protected API functionality by including the 'api' substring in the URL, with the /api/gpt endpoint specifically exposed without authentication. The flaw carries a CVSS 8.3 with scope change and affects a web management interface for HAProxy, Nginx, Apache, and Keepalived, and no public exploit has been identified at time of analysis. No vendor-released patch exists at time of publication, making this a high-priority issue for any internet-exposed installation.
Authentication bypass in Erlang/OTP's TLS distribution module (inet_tls_dist) lets any attacker holding a TLS certificate signed by a CA in the node's trust store gain full Erlang distribution access, including remote code execution via rpc:call/4 and code:load_binary/3. The flaw stems from check_ip/1 inspecting the local socket address (inet:sockname/1) instead of the peer's address (inet:peername/1), so the LAN-allowlist subnet comparison always matches. No public exploit identified at time of analysis, but the one-line root cause is fully disclosed in the upstream fix commit.
Unauthenticated SQL data exfiltration in Aix-DB versions up to and including 1.2.4 allows attackers on adjacent networks to issue arbitrary SELECT queries against the application's database through the /llm/process_llm_out endpoint, which omits the token validation enforced on every other application route. The flaw was disclosed by CERT-PL and currently has no public exploit identified at time of analysis, but the CVSS 4.0 vector (AV:A/AC:L/PR:N/UI:N/VC:H) reflects trivial exploitation once an attacker reaches the deployment network. No vendor-released patch identified at time of analysis.
Privilege escalation in Lenovo Smart Connect for Windows allows a local authenticated user to bypass authentication checks and execute arbitrary code with elevated privileges. The flaw stems from an authentication bypass weakness (CWE-290) in the Windows client and carries a CVSS 4.0 score of 7.3. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in Lenovo Accessories and Display Manager for Enterprise on Windows allows an authenticated low-privileged user to execute arbitrary code with elevated privileges, per a Lenovo-disclosed internal finding (LEN-213623). The CVSS 4.0 base score of 8.5 reflects high impact to confidentiality, integrity, and availability of the vulnerable system, though no public exploit identified at time of analysis. The CWE-306 (Missing Authentication for Critical Function) classification combined with the 'Authentication Bypass' tag suggests a privileged operation in the product is reachable without proper access checks.
Roxy-WI 8.2.6.4 and prior exposes a broken object-level authorization flaw in its audit history endpoint, allowing any authenticated user to read any other user's full action audit trail. The GET /history/user/<server_ip> endpoint conflates the server_ip path parameter with a user identifier and performs no authorization check, meaning a guest account in an unrelated group can enumerate administrators' operational history including server IPs touched, configs deployed, and services restarted. No patch is available at time of publication; no public exploit code or active exploitation has been identified.
Cross-tenant data tampering in Roxy-WI versions 8.2.6.4 and prior allows any authenticated user to silently overwrite HTTP, TCP, Ping, and DNS monitoring checks belonging to other tenants by sending a crafted PUT /smon/check request with another tenant's smon_id. The flaw stems from missing user_group authorization on the UPDATE SQL path (CWE-639, IDOR), while the DELETE path is correctly filtered - confirming the maintainers knew the right pattern but failed to apply it on update. No public exploit identified at time of analysis, and no vendor-released patch is available, raising operational risk for multi-tenant deployments.
Privilege escalation in Roxy-WI versions 8.2.6.4 and prior allows any authenticated user - including the lowest-privilege 'guest' role 4 - to start, stop, or restart the roxy-wi-smon-agent systemd unit on arbitrary managed servers, with the action executing as root via Roxy-WI's passwordless sudo SSH credentials. The flaw stems from missing role and group-ownership checks on the agent_action endpoint, and no public exploit has been identified at time of analysis though the vulnerability is trivially reachable once an account exists.
Privilege escalation and cross-tenant compromise in Roxy-WI versions 8.2.6.4 and prior allows any authenticated user - including the default guest role 4 - to install or reconfigure exporters, WAF, and GeoIP databases on every managed server regardless of tenant ownership. Because the affected installer endpoints lack role and group decorators, low-privilege users can pivot through stored SSH credentials with sudo to achieve root-level command execution on HAProxy/Nginx/Apache hosts belonging to other tenants. No public exploit identified at time of analysis, but the issue is unpatched and rated CVSS 9.9.
{id}/image-url` endpoint to obtain presigned S3 download URLs for OVA images belonging to other users/organizations. The leaked OVA contains long-lived agent JWTs and source configuration, enabling cross-tenant takeover of victim sources. No public exploit identified at time of analysis, but the upstream fix in PR #1218 confirms the access-control gap.
Credential interception in kubev2v assisted-migration-agent allows network-positioned attackers to harvest vCenter administrator credentials because the agent's vCenter client establishes TLS connections with certificate verification effectively disabled by default. The flaw, reported by Red Hat and tracked as EUVD-2026-36032, has no public exploit identified at time of analysis and an EPSS score of 0.01% (percentile 1%), but successful MITM exploitation yields full administrative access to the targeted vCenter.
Cross-tenant data tampering in kubev2v migration-planner allows an authenticated agent token holder to overwrite inventory and status data belonging to other tenants. The agent-API middleware accepts any valid JWT without verifying the token's source_id claim matches the source ID in the UpdateSourceInventory and UpdateAgentStatus request paths, enabling complete tenant isolation collapse. No public exploit identified at time of analysis, but the upstream fix in PR #1213 (kubev2v/migration-planner) confirms the issue is real and trivially exploitable given a low-privileged agent token.
Mass data deletion in Red Hat's kubev2v migration-planner SaaS platform allows attackers to wipe all customer sources, agents, and assessments via an unprotected DELETE /api/v1/sources endpoint. The endpoint lacks both authorization checks and tenant filtering, so a single request destroys data across the entire multi-tenant deployment. No public exploit identified at time of analysis, but the upstream fix (PR #1227) removes the endpoint entirely, confirming the issue is real and trivially reachable.
Authentication bypass in dhax/go-base Go REST API boilerplate (versions prior to commit cc82b974, merged May 17, 2026) allows remote unauthenticated attackers to forge JWT tokens for arbitrary users including administrators. The signing secret is hardcoded to the literal string 'random' in both the dev.env template and as a Viper default in cmd/serve.go, and publicly available exploit code exists in the advisory. No CISA KEV listing or EPSS data is provided, but the secret is trivially derivable from the public GitHub repository.
Policy bypass in @hulumi/policies versions prior to 1.4.0 allows an unhardened raw AWS S3 bucket to pass the HULUMI-H5 defence-in-depth check by pairing it with five decoy sibling hardening resources that reference a different bucket. Consumers of HulumiHardeningPack can ship S3 buckets with no public-access block, no SSE-KMS encryption, no ownership controls, no versioning, and no TLS-only bucket policy while the policy pack reports the stack as compliant. No public exploit identified at time of analysis, though the upstream fix and regression tests publicly document the bypass technique.
Policy enforcement bypass in @hulumi/policies versions prior to 1.4.0 allows infrastructure developers to ship raw cloud resources (AWS S3 buckets, GitHub repositories, Cloudflare zones and DNS records) that evade mandatory hardening checks by embedding a trusted parent-component substring inside the developer-controlled logical-name portion of a Pulumi URN. The flaw is a CWE-693 Protection Mechanism Failure spanning six policy packs (DEPLOY_GOV_1, AWS H4/H5, GitHub H1/H2, Cloudflare CF_DNS_1/CF_DNSSEC_1) where exemption logic used a naive substring match instead of structural URN parsing. No public exploit identified at time of analysis, though the spoofing technique is described in detail in the published advisory.
Missing authorization checks in Jenkins 2.567 and earlier (LTS 2.555.2 and earlier) expose user-specific configuration data to any authenticated user holding the Overall/Read permission. Authenticated low-privilege users can query the timezone setting of any Jenkins user account and enumerate the names of views configured within other users' 'My Views' personal dashboards, constituting an information disclosure weakness. No public exploit code exists and this CVE is not listed in the CISA KEV catalog at time of analysis, placing real-world risk in the low-moderate tier primarily relevant to multi-tenant or shared Jenkins deployments.
Missing authorization enforcement in Jenkins allows low-privileged authenticated users to cancel build queue items they lack permission to view. Affecting Jenkins 2.567 and earlier (LTS 2.555.2 and earlier), this CWE-862 flaw breaks the expected access control invariant that Item/Cancel should be constrained by Item/Read visibility. No public exploit code exists and this vulnerability is not listed in CISA KEV at time of analysis, but the low attack complexity and network accessibility make it a realistic threat in multi-tenant Jenkins deployments where fine-grained RBAC is in use.
Authentication bypass in NSA Ghidra versions prior to 12.1 allows any holder of a valid CA-signed certificate to impersonate arbitrary users by submitting their public certificate alongside a null signature to PKIAuthenticationModule.authenticate(). Successful exploitation yields privilege escalation, tampering of repository access controls, exfiltration of shared reverse-engineering databases, and persistent compromise of the Ghidra server. No public exploit identified at time of analysis, but a vendor patch and detailed advisory from VulnCheck are available.
Local privilege escalation in Slate Digital Connect 1.37.0 for macOS allows unprivileged users on the host to gain root-level capabilities by abusing a TOCTOU race in the privileged helper's XPC client validation. The com.slatedigital.connect.privileged.helper.tool2 service identifies callers by PID and then queries code-signing information, but PID reuse lets an attacker substitute a trusted process between check and use. No public exploit identified at time of analysis, and EPSS is very low (0.02%), but the technical pattern is well-known on macOS and a SEC Consult advisory describes the flaw in detail.
Local privilege escalation in Slate Digital Connect 1.37.0 for macOS allows unprivileged users to execute commands as root by connecting to the privileged XPC helper service with a self-signed certificate whose subject OU matches the expected value. The flaw stems from improper certificate validation (CWE-296) in the helper's client authorization logic, which fails to verify the certificate chains to a trusted code-signing authority. No public exploit is identified in CISA KEV at time of analysis, and EPSS reflects very low (0.01%) near-term exploitation probability, but a detailed vendor-lab advisory is publicly available.
Missing authorization controls on Debusine's artifact relationship endpoints allow remote actors to create and delete artifact relationships without holding the necessary write permissions, affecting all versions from 0.2.0 through 0.14.5. The only implicit gatekeeping was visibility of the referenced artifacts - not modification rights - a CWE-862 (Missing Authorization) flaw that exposes both data integrity and limited confidentiality of build artifact metadata. No public exploit code exists and EPSS places exploitation probability at 0.01% (3rd percentile), reflecting the tool's niche deployment scope within Debian build infrastructure; the vulnerability is not confirmed actively exploited (CISA KEV).
Authorization bypass in QNAP File Station 5 (versions 5.5.0 through 5.5.6.5243) allows a remote attacker with a valid low-privileged user account to circumvent intended access restrictions and reach files or operations they should not be able to access. The flaw was reported by QNAP itself with a CVSS 4.0 score of 8.6 reflecting high confidentiality and integrity impact, and there is no public exploit identified at time of analysis. Note that the vendor description text references 'File Station 6,' but the CPE, affected version list, and fix data all point to File Station 5, which appears to be a typo in the advisory.
Unauthorized data access and action execution in QNAP QuMagie versions prior to 2.9.0 allows remote attackers to bypass authorization checks and interact with resources they should not be permitted to reach. The flaw is classified as a missing authorization issue (CWE-862) and carries a CVSS 4.0 score of 8.7 due to its network-reachable, low-complexity nature with no privileges or user interaction required. No public exploit identified at time of analysis, but QNAP NAS appliances are historically high-value targets for opportunistic attackers.
Insecure direct object reference in BuddyPress 14.4.0's friends REST API exposes any authenticated attacker's ability to enumerate the complete friend list of any arbitrary user on the platform. The root cause is a missing ownership check in the `get_items_permissions_check` method, which validates only that the requester is logged in - not that they have authorization to view the target `user_id`'s social connections. No public exploit has been identified at time of analysis, and this vulnerability is not listed in CISA KEV, but the low attack complexity and broad applicability to any authenticated user on affected WordPress installations make it a genuine privacy risk for communities using BuddyPress's social networking features.
Insecure direct object reference in BuddyPress 14.4.0's messages REST API lets any authenticated WordPress user read, reply to, or delete another user's private message threads by supplying a target user_id parameter. The flaw originates in get_item_permissions_check, which trusts the attacker-supplied identifier instead of the authenticated session, and the same broken check is reused by update and delete handlers. No public exploit identified at time of analysis, but the simplicity of the request manipulation and CVSS 4.0 base of 8.6 mark this as a high-priority issue for any community site running BuddyPress.
Authentication bypass via X.509 certificate impersonation in Spring Security affects versions 5.7.0-5.7.24, 5.8.0-5.8.26, 6.3.0-6.3.17, 6.4.0-6.4.17, and 6.5.0-6.5.10, where the SubjectDnX509PrincipalExtractor mishandles malformed Common Name (CN) values and resolves the principal to the wrong identity.
