Hi, The following vulnerability was published for librest. CVE-2026-16615[0]: | 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 the pseudo-random | number generator (PRNG) seed to predict or reconstruct the code | verifier string, allowing an attacker to bypass PKCE protections and | successfully impersonate the client during the OAuth 2.0 | authorization flow. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
