JLSEC-2026-108 Deno's AES GCM authentication tags are not verified

Summary This affects AES-256-GCM and AES-128-GCM in Deno, introduced by commit 0d1beed. Specifically, the authentication tag is not being validated. This means tampered ciphertexts or incorrect keys might not be detected, which breaks the guarantees expected from AES-GCM. Older versions of Deno...

Name constraints for URI names were incorrectly accepted

Name constraints for URI names were ignored and therefore accepted. Note this library does not provide an API for asserting URI names, and URI name constraints are otherwise not implemented. URI name constraints are now rejected unconditionally. Since name constraints are restrictions on otherwis...

Name constraints were accepted for certificates asserting a wildcard name

Permitted subtree name constraints for DNS names were accepted for certificates asserting a wildcard name. This was incorrect because, given a name constraint of accept.example.com, .example.com could feasibly allow a name of reject.example.com which is outside the constraint. This is very simila...

Improper Certificate Validation

Apache Log4j Core is vulnerable to Improper Certificate Validation. The vulnerability is due to ignored hostname verification settings in TLS configuration, which allows an attacker to perform a man-in-the-middle attack by presenting a trusted certificate and intercepting secure communications...

CLSA-2026-1776159098 Fix CVE(s): CVE-2025-30258

SECURITY UPDATE: signature verification DoS via malicious subkey - debian/patches/CVE-2025-30258.patch: require signing usage when looking up public key for signature verification, filtering out subkeys without valid backsig. Include upstream regression fixes to preserve verification of signature...

CVE-2026-35040

fast-jwt provides fast JSON Web Token JWT implementation. Prior to 6.2.1, using certain modifiers on RegExp objects in the allowedAud, allowedIss, allowedSub, allowedJti, or allowedNonce options in verify functions can cause certain unintended behaviours. This is because some modifiers are statef...

CVE-2026-32605

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.3.0, an untrusted peer could crash a validator by publishing a signed tendermint proposal message where signer == validators.numvalidators...

CoinMate.io: HMAC signature verification omits endpoint and payload allowing request forgery on CoinMate API

A vulnerability was discovered in the HMAC signature verification process of the CoinMate API. The signature was calculated using only the nonce, client ID, and public key, omitting the HTTP endpoint and request payload. This allowed an attacker to hijack a valid signature intended for a read-onl...
