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 (31296)
Cross-project issue state modification in Bugsink prior to 2.2.0 allows authenticated users with access to one project to alter the state of issues belonging to other projects if a valid target issue UUID is known. The bulk action endpoint authorizes based on the project in the URL but applies submitted issue IDs without verifying project membership, creating a project-boundary authorization bypass. No active exploitation has been confirmed (not in CISA KEV), no public exploit code has been identified, and the EPSS score of 0.03% (8th percentile) reflects minimal real-world exploitation probability.
Cross-project event data exposure in Bugsink prior to 2.2.0 allows an authenticated user with access to one project to read event data - including stacktraces, breadcrumbs, and raw event details - belonging to a separate, unauthorized project. The flaw (CWE-639) exists because issue event views accept a direct event UUID from the URL without verifying that the event belongs to the project in the same URL path. Exploitation is materially constrained by the requirement for both an authenticated session and prior knowledge of a valid target event UUID; no public exploit has been identified and EPSS sits at 0.03% (7th percentile).
Cross-project sourcemap and debug-file disclosure in Bugsink prior to 2.2.0 allows an authenticated user with access to one project to read source context or symbolication-derived data belonging to a separate project on the same instance. The root cause is a missing authorization scope check (CWE-862): debug IDs supplied by clients were resolved globally rather than constrained to the owning project, meaning a deliberate or accidental debug ID collision across projects leaks file metadata. No public exploit code exists and no active exploitation has been identified (CISA KEV: absent, EPSS: 0.03%, 7th percentile), making this a low-urgency but architecturally meaningful information disclosure for multi-project Bugsink deployments.
Incorrect authorization in Traccar's DeviceResource.uploadImage endpoint allows authenticated low-privilege users to overwrite device image files on the server, bypassing readonly and deviceReadonly access restrictions that all other device mutation paths correctly enforce. Traccar versions prior to 6.13.0 are affected, and the root cause is a missing permissionsService.checkEdit call in the image upload route that is present everywhere else in the mutation surface. A proof-of-concept exists per SSVC data, though EPSS sits at 0.03% (9th percentile), indicating limited real-world exploitation activity to date. The vendor-released fix is available in version 6.13.0.
Default manufacturing credentials persisting through installation in IBM Cloud Pak for Data System Cyclops 11.3.0.2 through Interim Fix 002 allow unauthenticated network attackers to bypass authentication and perform unauthorized integrity-impacting actions. The root cause (CWE-1392) reflects a design-phase failure where credentials intended solely for factory/installation use are not forced to rotate before or immediately after deployment. EPSS sits at 0.03% and SSVC records no current exploitation, but the SSVC automatable flag indicates this class of attack is trivially scriptable, making exposed instances a realistic target for opportunistic credential-stuffing against known IBM default password sets. No public exploit identified at time of analysis.
Improper access control in sambitraj's STUDENT-MANAGEMENT-SYSTEM exposes multiple Dashboard endpoints to unauthenticated remote attackers, enabling unauthorized read and write operations on student data. The vulnerability, tagged as an authentication bypass (CWE-284), affects all code up to and including commit 56ba287f2e9031523ccb4244cb6e3fe530e4e5d5 and is confirmed by a publicly disclosed exploit via GitHub issue. No public exploit identified at time of analysis for active KEV-level exploitation, however publicly available exploit code exists and the maintainer has not responded to responsible disclosure, leaving the codebase unpatched.
CSRF protection bypass in e107 CMS prior to 2.3.5 allows unauthenticated remote attackers to perform unauthorized comment moderation actions by tricking an authenticated user into visiting a malicious page. The root flaw is in session_handler::check(), which skips CSRF token validation entirely when no token is submitted, rather than rejecting the tokenless request - effectively making CSRF protection opt-in from the attacker's perspective. A proof-of-concept exists per SSVC data; the vulnerability is not listed in CISA KEV and carries a very low EPSS score of 0.01% (3rd percentile), indicating limited observed exploitation in the wild.
Broken access control in e107 CMS prior to version 2.3.4 permits any low-privileged authenticated user to overwrite comments authored by other users, including administrators. The server-side updateComment() function in comment_class.php accepted a comment_id from the request and issued an UPDATE SQL query filtered only by that identifier, never verifying that the requesting user owned the targeted comment. A proof-of-concept exploit exists per SSVC data, though EPSS stands at a low 0.03% (8th percentile) and no active exploitation is confirmed in CISA KEV, indicating currently limited in-the-wild activity.

Szafir SDK returns a success status code from the cryptographic digital signature verification process (i.e. /VerifyingTaskItem/Signature/VerificationResult/Result/@code == 0, "Positively verified") even when the trust status of the signer's certificate could not be established (i.e. /VerifyingTaskItem/Signature/VerificationResult/SigningCertificate/@certificateType == "nondetermined"). This causes consuming applications to incorrectly treat the signature as valid despite an unverified certificate chain, enabling authentication bypass and user impersonation. This issue was fixed in version 463.
LDAP filter injection in Apache Airflow FAB Auth Manager (apache-airflow-providers-fab < 3.6.4) enables unauthenticated remote attackers to manipulate LDAP query logic by embedding special characters in login credentials, resulting in directory data exfiltration or authentication bypass. The vulnerability is confirmed by source code evidence: the `_search_ldap` and `_ldap_get_nested_groups` methods in `override.py` directly interpolated user-supplied input into LDAP filter strings without sanitization. No public exploit code has been identified at time of analysis and CISA KEV does not list this CVE, but the SSVC framework marks it as automatable, meaning exploitation can be scripted at scale against exposed Airflow instances using LDAP auth.
OutSystems Lifetime is vulnerable to Authorization Bypass Through User-Controlled Key vulnerability in ApplicationID parameter.

The vulnerability resides in RelayMidjourneyImage and GetByOnlyMJId functions within relay-router.go. Despite high attack complexity (CVSS AC:H) and CVSS score of only 3.7, a publicly available proof-of-concept exploit exists (disclosed via GitHub Gist), reducing the technical barrier. The vendor did not respond to early disclosure attempts. EPSS data not provided, but the combination of public exploit and unauthenticated network access (PR:N) warrants attention for organizations using this API gateway for Midjourney integration.
Unauthorized order manipulation and information disclosure in the WooCommerce PayPal Payments WordPress plugin (versions through 4.0.1) allows remote unauthenticated attackers to abuse two WC-AJAX endpoints (ppc-create-order and ppc-get-order) that lack authorization checks. By chaining these endpoints, an attacker can create a PayPal order against any victim's WooCommerce order ID and then retrieve full PayPal order details including payer information and shipping data. No public exploit identified at time of analysis, but the plugin's broad e-commerce deployment and trivial attack complexity make this a credible target.
Privilege escalation in Arcane Docker management platform (backend <= 1.19.1) allows any authenticated non-admin user to overwrite the system-wide .env.global file via the PUT /api/environments/{id}/templates/variables endpoint, which lacks the checkAdmin() guard applied to every other admin-sensitive handler. Because global variables are merged into every project's compose file at deploy time, an attacker can redirect image pulls to a malicious registry to achieve cross-tenant supply-chain code execution on the Docker host, steal credentials from other users' deployments, or break every project on the instance. No public exploit identified at time of analysis, but the GHSA advisory documents the exact vulnerable code path.
Privilege escalation in Nezha Monitoring (>= 1.4.0, < 1.14.15-0.20260517022419-d7526351cf97) lets an authenticated RoleMember invoke arbitrary cron tasks owned by other users - including admins - by referencing their task IDs in an alert rule's FailTriggerTasks/RecoverTriggerTasks fields. When the attacker's alert trips, the admin's cron command fans out to every connected agent, yielding cross-tenant command execution across the entire monitored fleet. EPSS is very low (0.04%), no public exploit identified at time of analysis beyond the PoC embedded in the GHSA advisory, and the vendor has shipped a patched commit.
Server-side request forgery in Nezha Monitoring dashboard (versions >=1.4.0, <1.14.15-0.20260517022419-d06d539d34c1) allows authenticated low-privilege RoleMember accounts to issue arbitrary HTTP requests to intranet targets via the POST /api/v1/notification and PATCH /api/v1/notification/:id endpoints, with full unbounded response bodies reflected back through error messages. Publicly available exploit code exists in the GHSA advisory, though EPSS is 0.03% (9th percentile) suggesting low mass-exploitation likelihood against this niche server-monitoring tool. Root cause is a missing adminHandler authorization gate combined with a notification webhook tester that ignores private/loopback CIDRs and lacks an io.LimitReader.
Privilege escalation in Microsoft Entra ID enables remote unauthenticated attackers to bypass origin validation and gain elevated privileges across tenant boundaries (scope-changed). The CVSS 10.0 rating reflects maximum impact across confidentiality, integrity, and availability with no authentication or user interaction required, though no public exploit has been identified at time of analysis and EPSS data is not provided.
Authentication bypass in Microsoft Azure Active Directory B2C (now part of Microsoft Entra) allows remote unauthenticated attackers to elevate privileges by reaching protected functionality through an alternate code path. The CVSS 9.1 vector (AV:N/AC:L/PR:N/UI:N) reflects network-reachable exploitation with no privileges and no user interaction, yielding high confidentiality and integrity impact against tenants relying on Azure AD B2C for identity. No public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the unauthenticated-network profile and Microsoft self-reporting make this a high-priority advisory for any tenant using B2C.
Privilege elevation in Microsoft Azure Resource Manager (ARM) allows remote unauthenticated attackers to bypass authentication and gain elevated privileges across the cloud control plane. The flaw carries a maximum CVSS score of 10.0 due to a scope change combined with full confidentiality, integrity, and availability impact, and although Microsoft has released a fix there is no public exploit identified at time of analysis. Given ARM is the central management layer for nearly all Azure resources, successful exploitation could have broad tenant-wide consequences.
Privilege escalation in Microsoft Azure Privileged Identity Management (PIM) allows an authenticated attacker to bypass authorization checks by manipulating a user-controlled key, escalating privileges over the network. The flaw stems from an Insecure Direct Object Reference (IDOR) pattern (CWE-639) where the service trusts a client-supplied identifier when making authorization decisions. No public exploit identified at time of analysis, and the vulnerability is not currently listed in CISA KEV.
Authentication bypass in Best Practical's Request Tracker (RT) versions 5.0.9 and prior, and 6.0.0 through 6.0.2, allows remote attackers to log in as any LDAP-backed user without valid credentials when RT is configured with LDAP or Active Directory authentication and the LDAP server accepts unauthenticated bind requests. The flaw, fixed in RT 5.0.10 and 6.0.3 released 2026-05-20, carries a CVSS 8.1 and has no public exploit identified at time of analysis, but the trivial nature of the bypass against vulnerable LDAP policies makes it high-priority for any RT deployment using directory-based auth.
Missing HMAC signature validation on Typebot's WhatsApp Cloud API webhook endpoint exposes versions 3.16.0 and prior to unauthenticated webhook spoofing by any network-accessible attacker. The endpoint POST /v1/workspaces/{workspaceId}/whatsapp/{credentialsId}/webhook ignores the x-hub-signature-256 header that Meta includes with every legitimate delivery, and because both path parameters are semi-public by design - appearing in web server access logs and Meta's webhook configuration dashboard - the attack surface is readily discoverable. Successful exploitation allows an attacker to trigger arbitrary bot automation flows, consume API resources, and abuse external service integrations using the workspace owner's stored credentials. No public exploit identified at time of analysis; vendor-released patch available in version 3.17.0.
Cross-typebot result data leakage in Typebot versions 3.15.2 and prior allows an authenticated user to read session variables, prior answers, and PII from a different typebot by supplying a foreign resultId to the startChat endpoint. The bot engine's findResult query omits typebotId from its database filter (CWE-639 IDOR), so any valid result record is returned regardless of which typebot owns it. If the attacker possesses a valid CUID2 resultId from another typebot and that typebot has rememberUser enabled, they can read the original user's names, emails, phone numbers, and other session variables exposed through matching variable names. No public exploit has been identified at time of analysis; vendor-released patch is available in version 3.16.0.
Enhanced Container Isolation (ECI) bypass in Docker Desktop allows a local low-privileged user with Docker CLI access to mount the Docker Engine socket into a container by invoking the --use-api-socket flag, granting full Docker Engine control and exposure of registry credentials. The flaw stems from the API proxy inspecting only HostConfig.Binds while the flag routes the mount through HostConfig.Mounts, slipping past ECI policy. No public exploit identified at time of analysis, but the issue was reported by Docker itself and disclosed via ZDI (ZDI-26-299).
Authorization bypass in Typebot chatbot builder versions 3.15.2 and prior allows any authenticated user to access credentials from arbitrary workspaces via the preview chat endpoint. The bot-engine's getCredentials() utility uses a falsy check on workspaceId, so supplying an empty string bypasses ownership validation entirely, enabling credential theft, external service abuse, and data breach. This is an incomplete fix for the prior advisory GHSA-4xc5-wfwc-jw47, and no public exploit has been identified at time of analysis though the patch commit is public.
Typebot 3.15.2 exposes complete private bot definitions across all workspaces to any authenticated platform user via a broken authorization check in the getLinkedTypebots API endpoint, constituting a classic IDOR. The root cause is a JavaScript async/await misuse: Array.filter() is synchronous, so passing it an async callback causes every bot to pass the filter - the isReadTypebotForbidden predicate is never actually evaluated. Sensitive data leaked includes embedded credentials, API keys, PII stored as variables, webhook URLs, and integration configurations from any other user's private workspace bots. No public exploit has been identified at time of analysis and this CVE is not listed in CISA KEV, but the exposure of hardcoded secrets elevates practical risk significantly beyond the 6.5 CVSS score suggests.
Session freshness bypass in Flask-Security-Too 5.8.0 allows an attacker who controls a stale authenticated victim session to satisfy the victim session's reauthentication requirement using their own OAuth identity, not the victim's. The flaw in `oauth_glue.py` causes `oauth_verify_response()` to update `session["fs_paa"]` (the freshness timestamp) without verifying that the OAuth-resolved user matches the currently authenticated session user. Exploitation was confirmed via a detailed proof-of-concept that successfully changed a victim user's username through the built-in `/change-username` route after bypassing the freshness gate. Publicly available exploit code exists; no CISA KEV listing at time of analysis.
Authentication bypass in LizardByte Sunshine self-hosted game stream host (versions prior to 2026.516.143833) allows remote unauthenticated attackers to bypass client-certificate authentication and access protected HTTPS endpoints. The custom OpenSSL verification callback in src/crypto.cpp incorrectly treats several certificate validation errors as successful verification, enabling untrusted certificates to pass authentication. No public exploit identified at time of analysis, but the CVSS 9.8 rating reflects trivial network-based exploitation against default deployments.
Server-Side Request Forgery in Typebot chatbot builder versions 3.15.2 and prior allows unauthenticated remote attackers to abuse the preview chat endpoint to make arbitrary internal HTTP requests from the server. The flaw stems from the isolated-vm sandbox's fetch function calling Node.js native fetch without the SSRF validation (validateHttpReqUrl) that protects HTTP Request blocks, bypassing mitigations added after GHSA-8gq9-rw7v-3jpr. No public exploit identified at time of analysis, but the CVSS 10.0 (Critical) score with scope-changed impact indicates severe risk for both self-hosted and hosted deployments.
Authorization bypass in AWS Kiro CLI versions prior to 1.28.0 allows a local attacker to invoke arbitrary tools, including shell commands, without triggering the user approval prompt by piping crafted content through stdin. Reported by Amazon (AMZN) and tagged as an Authentication Bypass, this issue has a vendor-released fix in 1.28.0; publicly available exploit code exists is not indicated, and the SSVC framework currently records no observed exploitation despite a Total technical impact rating.
OAuth scope validation bypass in Mattermost's GitHub integration allows authenticated users to escalate repository access beyond what was originally authorized. By manipulating the scope parameter in the GitHub OAuth authorization URL before the callback is processed, a low-privileged Mattermost user can obtain a GitHub token with broader permissions - including access to private repositories - than the application intended to grant. Affecting versions across four active release branches (10.11.x through 11.6.x), this is no public exploit identified at time of analysis and is not listed in CISA KEV, but the low complexity and authentication-only barrier make it a realistic insider or compromised-account risk.
Insecure Direct Object Reference (IDOR) in Typebot's getResultLogs API endpoint allows any authenticated user to read execution logs belonging to other workspaces by supplying an arbitrary victim resultId alongside their own authorized typebotId. The endpoint authorizes the caller by typebotId but fetches log records by resultId alone, skipping cross-ownership validation that all peer endpoints in the same router correctly enforce. Exploitation exposes sensitive runtime data including HTTP response bodies, AI model outputs, and webhook payloads. No public exploit or CISA KEV listing has been identified at time of analysis, but the straightforward nature of the IDOR - requiring only a valid session and a guessed or enumerated resultId - makes unauthorized data access realistic for any authenticated platform user.
Missing authorization in the entry status management feature in Devolutions Server allows a non-administrator authenticated user to bypass the administrator-enforced Pending Approval flow and gain access to an entry's data via a crafted status change request. This issue affects : * Devolutions Server 2026.1.6.0 through 2026.1.16.0 * Devolutions Server 2025.3.20.0 and earlier
Improper access control in the entry activity log feature in Devolutions Server allows an authenticated user with access to an entry but without the required permission to retrieve that entry's activity logs via a crafted API request. This issue affects : * Devolutions Server 2026.1.6.0 through 2026.1.16.0 * Devolutions Server 2025.3.20.0 and earlier
Improper access control in the entry documentation and attachment features in Devolutions Server allows an authenticated user with vault read access to retrieve the documentation and attachments of sealed entries via a crafted API request. This issue affects : * Devolutions Server 2026.1.6.0 through 2026.1.16.0 * Devolutions Server 2025.3.20.0 and earlier
Missing authorization in the user profile update feature in Devolutions Server allows an authenticated Active Directory user to modify their own profile attributes via a crafted API request. This issue affects : * Devolutions Server 2026.1.6.0 through 2026.1.16.0 * Devolutions Server 2025.3.20.0 and earlier
Authorization bypass in the entry duplication feature in Devolutions Server allows an authenticated user with write access to any vault to copy documentation and attachments from an entry in a vault they cannot access via a crafted save request. This issue affects : * Devolutions Server 2026.1.6.0 through 2026.1.16.0 * Devolutions Server 2025.3.20.0 and earlier
Missing authorization in the vault import feature in Devolutions Server 2026.1.16.0 and earlier allows a low-privileged authenticated user to create new vaults via a crafted import request.
Improper handling of factor key state in the multi-factor authentication management feature in Devolutions Server allows an attacker with knowledge of a user's password to bypass the user's multi-factor authentication after the user reconfigures their factors. This issue affects : * Devolutions Server 2026.1.6.0 through 2026.1.16.0
Dell Unisphere for PowerMax vApp version prior to 10.0.0.2, contains an authorization bypass vulnerability in the Unisphere for VMAX application running in vApp. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity.
Dell ECS, versions 3.5 and 3.6, contain an Improper Access Control in the Identity and Access Management (IAM) module. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required.
Concrete CMS 9.5.0 and below is vulnerable to IDOR + wrong-authorization-level in the Express association Reorder dialog. This can cause Cross-entity state tampering with view-only permission on one entry. To be affected, a website has to be using express and relying on express entity ordering. The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 2.3 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Winston Crooker for reporting.
Dell PowerFlex Manager versions 4.6.2 and earlier improperly store sensitive information in a manner accessible to low-privileged local users, resulting in unauthorized disclosure of confidential data with high confidentiality impact per CVSS. Affected deployments span both the Appliance and Rack form factors of the platform. No public exploit code has been identified at time of analysis and CISA KEV does not list this vulnerability, though the CWE-922 root cause and the 'Authentication Bypass' tag suggest the exposed data may include credentials or tokens that could enable downstream privilege escalation or lateral movement.
Broken or risky cryptographic algorithm use in Dell PowerFlex Manager's SSH component (versions ≤4.6.2) allows a locally authenticated low-privileged attacker to bypass SSH protection mechanisms, affecting both Appliance and Rack form factors. The CVSS vector (AV:L/AC:H/PR:L) reflects significant exploitation barriers: physical or logical local access is required, attack complexity is high, and impact is limited to partial confidentiality and integrity loss with no availability impact. Dell has published dual advisories (DSA-2025-434 for Appliance, DSA-2025-435 for Rack); no public exploit or CISA KEV listing exists at time of analysis.
Insecure storage of sensitive information in Dell PowerFlex Manager versions up to and including 4.6.2 exposes credentials, keys, or configuration secrets to any attacker with local OS-level access to the appliance - no PowerFlex Manager authentication required. The CVSS vector (AV:L/AC:L/PR:N/UI:N) confirms the attacker needs only local system access, not application credentials, to retrieve the improperly protected data. No public exploit identified at time of analysis and no CISA KEV listing; however, the 'Authentication Bypass' tag in the intelligence data suggests the exposed sensitive material may itself enable downstream privilege escalation or authentication bypass against PowerFlex or its managed infrastructure.
File ownership and access control enforcement is absent in the Boards API across four release branches of Mattermost, allowing any authenticated user to access and download files belonging to other users or teams by submitting crafted API requests containing valid file IDs. Affected deployments span versions 10.11.x through 11.6.x per EUVD-2026-31429 and vendor advisory MMSA-2026-00620. CVSS scores this at 5.9 (Medium) reflecting high attack complexity due to the file ID prerequisite; no public exploit has been identified and the vulnerability is not listed in CISA KEV at time of analysis.
Broken access control in TeamViewer DEX Platform (On-Premises) before version 9.2 allows authenticated low-privileged users to invoke administrative API endpoints and access sensitive resources outside their authorized scope. The root cause is CWE-862 (Missing Authorization) - backend API endpoints omit proper role-based authorization checks despite confirming user identity. No public exploit code has been identified and this CVE is not listed in the CISA KEV catalog at time of analysis, but the network-accessible attack vector and low complexity make exploitation straightforward for any user holding valid platform credentials.
Unauthorized playlist data disclosure in the AudioIgniter WordPress plugin (≤2.0.2) allows remote unauthenticated attackers to retrieve track metadata for non-public playlists via the /audioigniter/playlist/{id}/ rewrite endpoint. The handle_playlist_endpoint() function validates only post_type, omitting authentication, capability, and post_status checks, so draft, private, pending, and trashed playlists are reachable by ID enumeration. No public exploit identified at time of analysis; the issue is fixed in version 2.0.3 per the vendor commit.
Authorization bypass in MotoPress Hotel Booking plugin for WordPress (all versions through 6.0.1) allows unauthenticated remote attackers to overwrite or delete internal booking notes for any reservation by supplying an arbitrary booking ID. The root cause is a nonce that is unconditionally output into every public page's HTML via wp_localize_script under MPHB._data.nonces, meaning any site visitor - without an account or any prior interaction - can obtain a valid nonce and invoke the update-booking-notes AJAX action against any booking. No public exploit code has been identified at time of analysis, but the trivially accessible nonce makes this effectively zero-friction to abuse.
Unauthorized data disclosure in the Ditty - Responsive News Tickers, Sliders, and Lists WordPress plugin (versions 0 through 3.1.65) allows unauthenticated remote attackers to retrieve the full contents of non-public Ditty entries - including drafts, pending, scheduled, and disabled posts - by enumerating integer post IDs against the ditty_init AJAX endpoint. The flaw stems from the init_ajax() handler omitting the 'publish' post status check that its non-AJAX counterpart performs, exposing content administrators deliberately withheld from public view. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
