PYSEC-2026-2695 Open WebUI: Cross-origin postMessage confirmation bypass via action:submit

Summary The chat message listener allows non-same-origin input:prompt and action:submit messages, so an external site can set prompt text and trigger submitPrompt in an authenticated victim session. I validated this with a cross-origin attacker page that auto-posted messages and caused unauthoriz...

Flask-Security-Too OAuth reauthentication freshness bypass via cross- user OAuth identity acceptance

Summary Flask-Security-Too 5.8.0's OAuth reauthentication flow can mark a session as fresh after verifying an OAuth account that belongs to a different user. If an attacker can operate an already-authenticated but stale victim session, they can complete OAuth verification using their own OAuth...

PYSEC-2026-2546 Keras has a Local File Disclosure via HDF5 External Storage During Keras Weight Loading

EUVD-2026-42966

ZITADEL is an open source identity management platform. Prior to 4.15.3, ZITADEL's external identity provider handler checks that the local user's email is verified but does not verify that the external IdP confirmed ownership of the same email before auto-linking by email, allowing a permissive...

CVE-2026-56666

ZITADEL before v4.15.3 permits auto-linking by email without confirming IdP ownership of the email. The external IdP handler validates the local email but not that the IdP confirms ownership, enabling linking a permissive provider account to a victim’s local account. This vulnerability is address...

CVE-2026-55604

DeepSeek MCP Server (DeepSeek V4) is vulnerable from v1.4.2 up to, but not including, v1.7.0. The issue stems from a process-global SessionStore that accepts caller-supplied session_id values without binding them to any authenticated principal or transport session. An attacker can enumerate activ...

Bitwarden Server before 2026.6.0 does not verify that the email in a POST /auth-requests/admin-request body belongs to the authenticated caller, allowing a low-privileged organization member to obtain another user's vault key and a victim-scoped access token by creating a Trusted Device Encryptio...

CVE-2026-60104

Bitwarden Server before 2026.6.0 is vulnerable to an authorization bypass in the admin/auth request flow. A low-privileged organization member can exploit a mismatch in the POST /auth-requests/admin-request handling to bind a Trusted Device Encryption request to an attacker-controlled public key,...

Bitwarden Server before 2026.6.0 does not verify that the email in a POST /auth-requests/admin-request body belongs to the authenticated caller, allowing a low-privileged organization member to obtain another user's vault key and a victim-scoped access token by creating a Trusted Device Encryptio...

EUVD-2026-42257

n8n before 2.8.0 contains a cross-site scripting vulnerability in the credential management flow where authenticated users can inject malicious JavaScript URLs into OAuth2 credential Authorization URL fields. Attackers can craft malicious credentials and trick victims into clicking the OAuth...

CVE-2026-56250

Capgo before 12.128.2 allows upload-scoped API keys to modify the mutable appversions.r2path field through PostgREST, enabling retargeting to arbitrary R2 bundle objects. Attackers can patch r2path to point to victim objects, soft-delete the attacker-controlled version, and trigger the...

CVE-2026-55438

Coder's workspace app CORS origin check can be bypassed via UUID-based subdomain spoofing. Prior to versions 2.29.17, 2.32.7, 2.33.8, and 2.34.2, subdomain-based proxy would bypass the same-owner CORS check when a workspace-name segment parsed as a UUID. The workspace could be resolved by ID with...

PYSEC-2026-1612 Synapse's invalid device keys degrade federation functionality

Impact Lack of validation for device keys in Synapse before 1.138.3 and in Synapse 1.139.0 allow an attacker registered on the victim homeserver to degrade federation functionality, unpredictably breaking outbound federation to other homeservers. Patches Patched in Synapse 1.138.3, 1.138.4,...

Langflow Authorization Bypass Through User-Controlled Key Vulnerability

Langflow contains an authorization bypass through user-controlled key vulnerability which allows an authenticated attacker to execute any flow belonging to another user by specifying the victim's flow ID in the request...
