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...

CVE-2026-16615: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

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...

Gitea: OAuth2 sign-in reactivates an administrator-deactivated account on auth sources without refresh tokens (incomplete fix of #38009)

Description Gitea's OAuth2 sign-in callback reactivates a deactivated user account IsActive=false when the user signs in through an authentication source that does not issue refresh tokens notably GitHub, and any OIDC/OAuth2 source configured without offlineaccess. PR 38009 added a gate intended ...

Cloudreve: OAuth access tokens bypass scope enforcement due to missing client_id claim

Summary Cloudreve's OAuth access tokens can bypass OAuth scope enforcement. This does not appear to be the intended design. The documentation describes OAuth client permissions/scopes, the API has an insufficient-scope error code, and the code comments say RequiredScopes... should verify scopes...
