CVE-2026-40323 SP1 V6 Recursion Circuit Row-Count Binding Gap

SP1 is a zero‑knowledge virtual machine that proves the correct execution of programs compiled for the RISC-V architecture. In versions 6.0.0 through 6.0.2, a soundness vulnerability in the SP1 V6 recursive shard verifier allows a malicious prover to construct a recursive proof from a shard proof...

BIT-AUTHENTIK-2023-48228 OAuth2: PKCE can be fully circumvented

authentik is an open-source identity provider. When initialising a oauth2 flow with a codechallenge and codemethod thus requesting PKCE, the single sign-on provider authentik must check if there is a matching and existing codeverifier during the token step. Prior to versions 2023.10.4 and 2023.8....

GHSA-JHM7-29PJ-4XVF @node-oauth/oauth2-server: PKCE code_verifier ABNF not enforced in token exchange allows brute-force redemption of intercepted authorization codes

Summary The token exchange path accepts RFC7636-invalid codeverifier values including one-character strings for S256 PKCE flows. Because short/weak verifiers are accepted and failed verifier attempts do not consume the authorization code, an attacker who intercepts an authorization code can...
