0 A vulnerability in librest's PKCE implementation for OAuth authorization uses a cryptographically insecure pseudo-random number generator (PRNG). This flaw allows attackers who can intercept the authorization code to reverse-engineer the PRNG seed, predict or reconstruct the code verifier string, and impersonate the client during the OAuth 2.0 authorization flow. The vulnerability has been rated with important severity and affects certain versions of librest. A security update is available to address this issue.

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.
