OAuth2 Proxy is a reverse proxy that provides authentication using OAuth2 providers. A regression introduced in 7.11.0 prevents OAuth2 Proxy from clearing the session cookie when rendering the sign-in page. In deployments that rely on the sign-in page as part of their logout flow, a user may be shown the sign-in page while the existing session cookie remains valid, meaning the browser session is not actually logged out. On shared workstations or devices, a subsequent user could continue to use the previous user's authenticated session. Deployments that use a dedicated logout/sign-out endpoint to terminate sessions are not affected. This issue is fixed in 7.15.2

CVE-2026-17600——
——0Sonatype Nexus Repository 3 did not immediately terminate a user's active login session or revoke their cached permissions when that user's account was deleted, deactivated, or had its password changed. A user whose account was already logged in at the time of one of these actions could continue using their existing session to interact with the repository as though the account were still active, until that session independently expired. Depending on the permissions previously held, this could allow continued unauthorized access to read, modify, or delete repository content after access was intended to be revoked.1dCVE-2026-480797.4 ALT31.4%
——9OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, when a user navigates to the `/logout` page, the page's server-side load handler deletes the `access_token` cookie before calling `/api/auth/logout` via an internal `event.fetch()`. The internal fetch consequently runs without the auth cookie, so `apiAuthHandle` rejects it, the logout handler never executes, and `SessionService.revokeSession()` is never called for the current session. The DB session row remains valid until its natural expiry (one week by default). The user sees a successful logout (cookie gone, UI returns to login), but any party still holding a copy of the now-deleted access token can continue making authenticated API calls until the session naturally expires. The root cause is a simple ordering mistake. The same auth subsystem implements the correct order in `/api/auth/logout`: revoke the current DB session first, then delete the cookie. The page-level wrapper does the opposite. Version 1.0.2 initiates server-side logout before removing authentication cookies and first appears in version 1.0.2. Version 2.0.0 later replaces this with a race-free client-side logout flow.1dCVE-2025-123175.0 MED15.1%
——5When internal roles are removed from a user within the WSO2 product, the system fails to invalidate any previously issued authentication tokens associated with that user.
This vulnerability could allow users to retain their previous access privileges even after their roles have been revoked. As a result, a user can continue to perform unauthorized actions or access restricted resources until the expired tokens naturally expire.1dCVE-2025-126272.4 BAJ3.0%
——1The user impersonation flow in WSO2 Identity Server fails to properly manage refresh tokens associated with impersonated sessions. This allows an attacker who has obtained an access token for an impersonated user to leverage the refresh token grant to obtain new access tokens, extending their ability to act as the legitimate user.
An attacker who gains access to an impersonated user's access token can exploit this weakness to renew their authorization. This results in the continued ability to perform actions on behalf of the actual user, compromising log integrity and traceability by masking the true actor.2dCVE-2024-89954.9 MED2.1%
——1Unused authorization codes issued to deleted users are not being properly invalidated or removed from the system. This allows for the persistence of these codes, enabling them to be potentially reused.
If an attacker possesses both the authorization code and the associated client credentials (client ID and client secret), they can leverage these unused codes to obtain access tokens on behalf of users who have already been deleted. This may lead to unauthorized access to sensitive resources and services, contingent on the scopes originally authorized for the compromised authorization code.2dCVE-2026-600539.1 CRÍ18.9%
——6Insufficient Session Expiration vulnerability in Apache Answer.
This issue affects Apache Answer: through 2.0.1.
Administrative API keys remained usable after the owning administrator was demoted or the account was marked inactive, suspended, or deleted, allowing continued access until the keys were explicitly removed.
Users are recommended to upgrade to version 2.0.2, which fixes the issue.1d
