CVE-2026-110008: Cross-Site Request Forgery (CSRF)

@fastify/oauth2 is a Fastify wrapper for OAuth2 login flows. In versions 7.2.0 through 8.3.1, the state and code-verifier cookies are set without a Path attribute at a login route with two or more path segments, while the clearing step at the OAuth callback writes them with a root path, so the...

@fastify/oauth2 Cross-Site Request Forgery Vulnerability

The @fastify/oauth2 version from 7.2.0 to 8.3.1 has security vulnerabilities. This vulnerability arises from not specifying the Path attribute when setting the state and code-verifier cookies for login routes. As a result, when OAuth callbacks clear these cookies, the original cookies remain afte...

CVE-2026-105638 Plane: Magic-code verifier endpoint has no rate limit, enabling 6-digit OTP brute force

Plane is an open-source project management tool. Prior to 1.4.0, Plane's magic-code email login uses a six-digit numeric OTP with approximately 20 bits of entropy. The verifier has no per-code failed-attempt counter, and an incorrect code does not increment a counter, invalidate the Redis entry, ...

CVE-2026-105638

The project management tool Plane is vulnerable to a 6-digit OTP brute force attack in versions prior to 1.4.0 . The magic-code email login verifier lacks a per-code failed-attempt counter, fails to invalidate Redis entries on incorrect attempts, and does not lock email addresses. Because the ver...

OESA-2026-3975 rest security update

This library has been designed to make it easier to access web services that claim to be "RESTful". It comprises of two parts: the first aims to make it easier to make requests by providing a wrapper around libsoup, the second aids with XML parsing by wrapping libxml2. Security Fixes: A flaw was...

librest: weak random number generation in PKCE implementation

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...

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...
