CVE-2026-59276: Observable Timing Discrepancy

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

Kanidm has non-constant-time comparison of OAuth2 client_secret

Summary The kanidmd OAuth2 token-exchange /oauth2/token and token-introspection /oauth2/token/introspect endpoints compare the supplied clientsecret against the stored secret using Rust's PartialEq on String, which short-circuits on the first mismatching byte. This produces an observable timing...

CVE-2026-41244: Observable Timing Discrepancy

Mojic is a CLI tool to transform readable C code into an unrecognizable chaotic stream of emojis. Prior to 2.1.4, the CipherEngine uses a standard equality operator !== to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy CWE-208,...
