Authentication Bypass Using an Alternate Path or Channel

OAuth2 Proxy is a reverse proxy that provides authentication using OAuth2 providers. Versions 7.5.0 through 7.15.1 have a configuration-dependent authentication bypass. Deployments are affected when all of the following are true: Use of `skip_auth_routes` or the legacy `skip_auth_regex`; use of patterns that can be widened by attacker-controlled suffixes, such as `^/foo/.*/bar$` causing potential exposure of `/foo/secret`; and protected upstream applications that interpret `#` as a fragment delimiter or otherwise route the request to the protected base path. In deployments that rely on these settings, an unauthenticated attacker can send a crafted request containing a number sign in the path, including the browser-safe encoded form `%23`, so that OAuth2 Proxy matches a public allowlist rule while the backend serves a protected resource. Deployments that do not use these skip-auth options, or that only allow exact public paths with tightly scoped method and path rules, are not affected. A fix has been implemented in version 7.15.2 to normalize request paths more conservatively before skip-auth matching so fragment content does not influence allowlist decisions. Users who cannot upgrade immediately can reduce exposure by tightening or removing `skip_auth_routes` and `skip_auth_regex` rules, especially patterns that use broad wildcards across path segments. Recommended mitigations include replacing broad rules with exact, anchored public paths and explicit HTTP methods; rejecting requests whose path contains `%23` or `#` at the ingress, load balancer, or WAF level; and/or avoiding placing sensitive application paths behind broad `skip_auth_routes` rules.Show less

ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the /api/public/user/login endpoint validates only the username and password before returning the user's API key, bypassing the normal authentication flow that enforces account lockout and two-factor authentication checks. An attacker with knowledge of a user's password can obtain API access even when the account is locked or has 2FA enabled, granting direct access to all protected API endpoints with that user's privileges. This issue has been fixed in version 7.2.0. Note: this issue had a duplicate, GHSA-472m-p3gf-46xp, which has been closed.Show less

An authenticated user with access to a kvv2 path through a policy containing a glob may be able to delete secrets they were not authorized to read or write, resulting in denial-of-service. This vulnerability did not allow a malicious user to delete secrets across namespaces, nor read any secret data. Fxed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0, 1.21.5, 1.20.10, and 1.19.16.Show less

The Visa Acceptance Solutions plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.1.0. This is due to the `express_pay_product_page_pay_for_order()` function logging users in based solely on a user-supplied billing email address during guest checkout for subscription products, without verifying email ownership, requiring a password, or validating a one-time token. This makes it possible for unauthenticated attackers to log in as any existing user, including administrators, by providing the target user's email address in the billing_details parameter, resulting in complete account takeover and site compromise.Show less

OpenClaw before 2026.3.25 contains an authentication bypass vulnerability in raw card send surface that allows unpaired recipients to mint legacy callback payloads. Attackers can send raw card commands to bypass DM pairing restrictions and reach callback handling without proper authorization.Show less

OpenClaw before 2026.3.25 contains an authorization bypass vulnerability in Telegram callback query handling that allows attackers to mutate session state without satisfying normal DM pairing requirements. Remote attackers can exploit weaker callback-only authorization in direct messages to bypass DM pairing and modify session state.Show less

OpenClaw before 2026.3.25 contains an authorization bypass vulnerability in Microsoft Teams feedback invokes that allows unauthorized senders to record session feedback. Attackers can bypass sender allowlist checks via feedback invoke endpoints to trigger unauthorized feedback recording or reflection.Show less

OpenClaw before 2026.3.25 contains an access control vulnerability where verification notices bypass DM policy checks and reply to unpaired peers. Attackers can send verification notices to users outside allowed direct message policies by exploiting insufficient access validation before message transmission.Show less

OpenClaw before 2026.3.25 contains an authorization bypass vulnerability where group reaction events bypass the requireMention access control mechanism. Attackers can trigger reactions in mention-gated groups to enqueue agent-visible system events that should remain restricted.Show less

OpenClaw before 2026.3.23 contains an authentication bypass vulnerability in the Canvas gateway where authorizeCanvasRequest() unconditionally allows local-direct requests without validating bearer tokens or canvas capabilities. Attackers can send unauthenticated loopback HTTP and WebSocket requests to Canvas routes to bypass authentication and gain unauthorized access.Show less

megagao production_ssm v1.0 contains an authorization bypass vulnerability in the user addition functionality. The insert() method in UserController.java lacks authentication checks, allowing unauthenticated attackers to create super administrator accounts by directly accessing the /user/insert endpoint. This leads to complete system compromise.Show less

In OpenAirInterface V2.2.0 AMF, Out of sequence messages causes incorrect state transition during UE registration procedure. This allows authentication to be bypassed completely. If a SecurityModeComplete message is sent after InitialUERegistration, a registration reject is received followed by a registration accept! This leads the UE to be registered without proper authentication.Show less

A vulnerability was detected in badlogic pi-mono up to 0.58.4. This issue affects some unknown processing of the file packages/mom/src/slack.ts of the component pi-mom Slack Bot. The manipulation results in authentication bypass using alternate channel. The attack can be executed remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less

goshs is a SimpleHTTPServer written in Go. From version 1.1.0 to before version 2.0.0-beta.2, when using the Share Token it is possible to bypass the limited selected file download with all the gosh functionalities, including code exec. This issue has been patched in version 2.0.0-beta.2.Show less
