CVE-2026-44909

Proxygen lacked a generalized slow-consumer detection mechanism in its core HTTP session layer. A remote, unauthenticated attacker could exploit HTTP/2 flow-control by setting SETTINGSINITIALWINDOWSIZE to 0 or withholding WINDOWUPDATE frames, causing the server to buffer complete response bodies ...

GHSA-7RQJ-J65F-68WH Auth.js: Email normalizer validates the address before Unicode normalization, allowing a homoglyph @ bypass

Summary The default email-address normalizer used by the email/magic-link sign-in flow validates the address before applying Unicode normalization. An address can contain a Unicode character that is not an ASCII @ U+0040 but canonicalizes to one under NFKC/NFKD normalization the normalization...

GHSA-X445-F3H2-J279 Auth.js: OAuth state, nonce, and PKCE check cookies are not bound to the provider that created them

Summary Auth.js stores the OAuth/OIDC anti-CSRF checks state, nonce, and the PKCE verifier in global cookies that are not bound to the provider that created them. On callback, a check value minted during a sign-in started with one provider can satisfy the callback for a different provider, becaus...

n8n: Member-Level Users Can Execute Other Users' MCP Server Trigger Workflows via Missing OAuth Authorization Check

Impact The OAuth 2.1 consent and token-issuance flow introduced in n8n 2.27.0 does not verify that the authenticated user has access to the workflow referenced as the OAuth resource. A member-level user can register an OAuth client, self-approve consent for another user's n8n OAuth2-protected MCP...

CVE-2026-64829

CVE-2026-64829 affects Question2Answer up to version 1.8.8. The issue is a session invalidation bug in the forgot-password flow: the handler qa_finish_reset_user() does not clear the sessioncode, allowing a previously issued remember-me cookie to continue authenticating the account after a passwo...

CVE-2026-14881

CVE-2026-14881 affects MongoDB Compass: during imports of connections, an attacker can override connection options that are not normally changeable via the connection form. Specifically, a custom browser open command for the OIDC authentication flow can be injected, which is typically configured ...

Compass connection import allows to override OIDC browser open command (usually set through settings), allowing for arbitrary shell commands execution when connecting to cluster using OIDC auth flow

When importing connections in Compass it is possible to override some connection options that are otherwise can't be changed via connection form. In particular it is possible to provide a custom browser open command for OIDC auth flow that is usually can be set only globally via Compass settings...

DEBIAN-CVE-2026-16615

A flaw was found in librest. The PKCE implementation for OAuth authorization uses the GRand function from the GLib API, a cryptographically insecure pseudo-random number generator. Because the generated "code verifier" lacks sufficient cryptographic entropy, a malicious actor can reverse-engineer...

CVE-2026-16615

The CVE affects librest where the PKCE implementation relies on GLib’s GRand PRNG, which is cryptographically insecure. This leads to insufficient entropy in the code verifier, enabling an attacker to reverse‑engineer the PRNG seed and predict or reconstruct the code verifier, thereby bypassing P...
