CVE-2026-86473 Critical · 9.1 CWE-613 Sep 21, 2026
Apache Airflow: Logout ignores a presented Authorization bearer token, leaving it revocable only by expiry
Apache Airflow: the Core API logout endpoint revokes only a session token presented as the _token cookie. When a client logs out presenting its credential as an Authorization bearer header instead, the endpoint returns its normal logout response but revokes nothing, so the token remains valid until it expires. An attacker who already holds a copy of that token keeps the victim's access after the victim has logged out and believes the session ended; the default token lifetime is 24 hours and is configurable. Affects API clients that authenticate with a bearer token rather than the browser session cookie. The attacker must already possess a copy of a valid token; obtaining one is outside the scope of this issue, and no privileges beyond the victim's own are gained. Users of apache-airflow are recommended to upgrade to apache-airflow version 3.3.2 or later, which fixes the issue.
CVE-2026-92976 Medium · 5.1 CWE-613 Sep 18, 2026
Stored Cross-Site Scripting (XSS) in T-Systems’ TAO 2.0
A stored Cross-Site Scripting (XSS) vulnerability in the profile management functionality of T-Systems’ TAO 2.0 suite. An authenticated user could inject malicious HTML or JavaScript content into the fields containing their personal data. The content entered is stored and displayed without being properly sanitised when another user, including administrative staff, views the affected profile. Successful exploitation could allow JavaScript code to be executed in the victim’s browser, access to information available within the session, or the performance of actions using the victim’s permissions.
CVE-2026-86533 Critical · 9.1 CWE-613 Sep 17, 2026
Revoked session accepted because the session jti is never checked in AshAuthentication and AshAuthentication Phoenix
Insufficient Session Expiration vulnerability in team-alembic AshAuthentication and AshAuthentication Phoenix allows a revoked session to remain fully authenticated. A resource configured with session_identifier :jti and require_token_presence_for_authentication? disabled stores its session value as <jti>:<subject>. The jti is there so that signing out can revoke that one session. Neither reader consults it: AshAuthentication.Plug.Helpers.authenticate_resource_from_session/4 and AshAuthentication.Phoenix.LiveSession.on_mount/4 both split the value with split_identifier/2, discard the jti and pass the bare subject to AshAuthentication.subject_to_user/3, which reloads the record. The token-presence branch of each function does check its token, calling AshAuthentication.TokenResource.Actions.get_token/3 with the jti and the purpose user. Because the revocation record is never read, neither its revoked state nor its expiry constrains the session, so a session captured before sign-out keeps working. This issue affects ash_authentication: from 4.9.1 before 4.15.0 and from 5.0.0-rc.0 before 5.0.0-rc.14; ash_authentication_phoenix: from 2.10.0 before 2.17.4 and from 3.0.0-rc.0 before 3.0.0-rc.11.
CVE-2026-81637 Low · 2.3 CWE-613 Sep 17, 2026
Replayable OAuth2 CSRF state retained after a failed callback in AshAuthentication
Insufficient Session Expiration vulnerability in team-alembic AshAuthentication allows an attacker who obtains a victim's OAuth2 state value to replay the callback and sign that victim into an attacker-controlled account. AshAuthentication.Strategy.OAuth2.Plug.callback/2 clears the stored session_params through a rebinding step inside its with chain, conn <- delete_session(conn, session_key). Elixir evaluates the else block in the scope enclosing the with, so every failure path (the provider returning ?error=access_denied, an invalid code, a token-exchange error, or a registration or sign-in failure) reaches store_authentication_result/2 holding the original connection and the session entry is never removed. The value the module's own comment describes as protection against a CSRF-related attack is therefore consumed only when authentication succeeds, and survives a cancelled or failed attempt until the next request phase or session expiry. This issue affects ash_authentication: from 0.6.0 before 4.15.0 and from 5.0.0-rc.0 before 5.0.0-rc.14.
CVE-2026-92920 Medium · 5.4 CWE-613 Sep 17, 2026
admin3 through 3.0.0 Session Not Invalidated When a User Account Is Disabled
admin3 through 3.0.0 fails to invalidate existing sessions when disabling a user account, allowing attackers to retain authenticated access with original permissions. Attackers can continue using bearer tokens issued before account disablement to authenticate requests, as the AuthInterceptor never re-validates the user's locked status and session expiry resets on each request.
CVE-2026-92800 Medium · 6.8 CWE-613 Sep 16, 2026
Docs before 5.4.1 Stale Collaboration Session After Access Revocation
Docs before 5.4.1 fails to properly revoke websocket collaboration connections when access is revoked at parent documents. Attackers with revoked access can retain real-time read and write access to sub-documents through open websocket sessions that are never disconnected.
CVE-2026-85387 High · 7.1 CWE-613 Sep 16, 2026
Concrete CMS before 9.5.4 allows a deactivated user to retain OAuth-authenticated REST API access
Concrete CMS before 9.5.4 re-authorized OAuth REST API requests from the bearer token alone and did not re-check the state of the account the token had been issued to. The resource server's authorization validator confirmed only that a token existed, had not expired, and had not been explicitly revoked, and deactivating a user did not revoke that user's outstanding tokens. As a result, a deactivated user retained full access to /ccm/api/1.0/* for the remaining lifetime of any token already issued to them. The same gap applied to accounts that had been deleted or locked pending a forced password reset. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 2.0 with vector CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks Myq Larson for reporting.
CVE-2026-92616 Medium · 6.8 CWE-613 Sep 16, 2026
FileRise < 3.28.0 Privilege Escalation via WebDAV Session Inheritance
FileRise before version 3.28.0 contains a privilege escalation vulnerability that allows authenticated low-privilege attackers to gain unauthorized read and write access by exploiting improper session isolation between the WebDAV interface and the web application session context. Attackers can combine valid Basic-Auth credentials with an active admin PHPSESSID cookie to bypass authorization boundaries, as the WebDAV layer incorrectly inherits elevated privileges from an ambient web session rather than enforcing independent stateless authentication per RFC 4918.
CVE-2026-82310 High · 7.2 CWE-613 Sep 16, 2026
Apache Airflow FAB provider: FAB auth manager: deactivated users retain and renew Core API JWT access
Apache Airflow FAB provider: deactivating a user account does not stop tokens issued to that account before deactivation. Password authentication correctly rejects the disabled account, but the Core API continues to accept an existing, unexpired token naming it, and lets that token mint a replacement — so the account keeps its role-scoped access indefinitely after an administrator has disabled it. The user replays their own legitimate credential; no signature forgery or privilege escalation is involved, and the access stays within the roles the account already held. Affects deployments using Airflow 3 with the FAB auth manager and Core API token authentication, where an administrator deactivates an account whose row remains in the database and whose previously issued token has not expired. The trigger is administrative deactivation as a containment action, which silently fails to contain. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which rejects tokens naming a deactivated account.
CVE-2026-86462 Critical · 9.1 CWE-613 Sep 16, 2026
Apache Airflow FAB provider: FAB Admin password PATCH does not invalidate database-backed sessions
Apache Airflow FAB provider: changing a user's password through the Admin user-edit PATCH endpoint does not invalidate that user's existing database-backed sessions. An attacker who already holds a copy of the victim's session cookie keeps full access as that user after the password change, so the password reset does not evict them. Affects deployments using the FAB auth manager with database-backed sessions; an administrator (or the user themselves) performing a routine password change is the trigger, and no attacker interaction with the endpoint is needed. This is a second, independent route to the outcome addressed by CVE-2026-82311, which corrected an identifier comparison in the session-invalidation helper. That fix does not repair this endpoint, because the PATCH path never calls the helper at all. Deployments that applied the CVE-2026-82311 fix must also upgrade for this one. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which fixes the issue.
CVE-2026-82311 Critical · 9.8 CWE-613 Sep 16, 2026
Apache Airflow FAB provider: FAB password reset never invalidates sessions: string/int _user_id comparison is always false
Apache Airflow FAB provider: resetting a user's password does not delete that user's existing database-backed sessions, despite documented behaviour that it does. The cleanup compares the string identifier Flask-Login stores in the session against the user's integer database identifier, so the comparison never matches and no session is removed. An attacker who already holds a copy of the victim's session cookie keeps access as that user after the password change, so the reset does not evict them. Affects deployments using the FAB auth manager with `[fab] session_backend=database`. The trigger is an administrator (or the user) running the supported password-reset command as a containment action after a session cookie has been compromised; the secure-cookie backend is out of scope, as it documents that it cannot centrally delete sessions. apache-airflow-providers-fab 3.9.0 also fixes CVE-2026-86462, a second, independent route to the same outcome via the Admin user-edit endpoint; a single upgrade closes both. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which compares the identifiers consistently.
CVE-2026-92358 Medium · 6.4 CWE-613 Sep 16, 2026
Keycloak-services: keycloak-services: residual cross-browser account-link proof allows silent re-linking
A flaw was found in the first broker login flow of Keycloak. When a user confirms an account-linking request from a different browser, a temporary proof is created to validate the link. However, this proof is not properly cleared after the link is established or when the user later manually removes the link. An attacker who controls the external identity can exploit this leftover proof to silently re-establish the link and gain unauthorized access to the victims account without any further confirmation.
CVE-2026-55617 Medium · 6.9 CWE-613 Sep 15, 2026
Hydro: Insufficient session expiration when recreating sessions
Hydro is a next-generation high-performance online judge platform. From 4.10.4 until 5.0.2, the session recreation logic in packages/hydrooj/src/service/layers/base.ts creates a replacement session token without deleting the previous token from the server-side session token store, so an old sid cookie can remain valid after logout or another renewal flow. An attacker who possesses a victim's previously valid stale cookie can replay it over HTTP or HTTPS without knowing the victim's username or password and without victim interaction at exploitation time. Successful replay can take over the victim's account, disclose private data, and permit unauthorized modification or deletion of data available to that account. This issue is fixed in version 5.0.2.

CVE-2026-87014 Medium · 6.5 CWE-613 Sep 9, 2026
Open WebUI: Admin demoted through SSO role sync keeps read and write access to all users' notes
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 until 0.11.1, role synchronization in backend/open_webui/routers/auths.py and backend/open_webui/utils/oauth.py updated an administrator's database role without invalidating the user record cached by backend/open_webui/socket/main.py. An administrator demoted through a trusted role header or OAuth role mapping could keep an already-open Socket.IO connection and continue reading or editing every user's collaborative notes until that connection closed. This issue is fixed in version 0.11.1.

CVE-2026-55513 Medium · 5.4 CWE-613 Sep 4, 2026
nebula-mesh: Web UI host creation ignores configured enrollment token TTL and mints 24-hour bearer enrollment tokens
nebula-mesh is a self-hosted control plane for Slack Nebula mesh VPN. From version 0.3.0 to before version 0.5.0, the nebula-mgmt Web UI host-creation path ignores both the server-wide enrollment_token_ttl security setting and per-network network_config.enrollment_token_ttl overrides. API host creation and token-regeneration paths use the configured TTL resolver, but POST /ui/hosts hardcodes now.Add(24 * time.Hour) for newly minted agent enrollment tokens. In deployments that intentionally reduce enrollment-token lifetime, any authenticated operator who can create a host through the Web UI can still mint a bearer enrollment token valid for about 24 hours. This issue has been patched in version 0.5.0.
CVE-2026-61608 Medium · 6.8 CWE-613 Sep 4, 2026
SolidInvoice's user invitation tokens have no expiry, allowing indefinite unauthorized company access via leaked or old invitation links
SolidInvoice is an open-source invoicing platform. Prior to version 3.0.1, `UserInvitation` entities have no expiry timestamp. Invitation links mailed to users remain valid indefinitely, meaning a leaked, forwarded, or archived invitation email can be used at any time in the future to join a company or silently add a compromised email account to a company. Version 3.0.1 fixes the issue.
