CVE-2026-18531: Use of Insufficiently Random Values
IBM Maximo Application Suite 9.2, 9.1, and 9.0 could allow a remote attacker to tamper with session data due to the use of a weak HMAC session signing secret...
python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens
A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

CVE-2026-11366
The MonsterInsights WordPress plugin (versions before 11.1.0 ) is vulnerable to an unauthenticated signature validation bypass. When the plugin is not connected to Google Analytics, the HMAC signing key is empty, allowing attackers to forge a valid signature. This enables unauthenticated actors t...

RUSTSEC-2026-0329 Auto-Reseeding HMAC-DRBG could panic for some output lengths
The automatically reseeding implementations of HMAC-DRBG would panic if called with a desired non-zero output length cleanly divisible by 65536, the maximum number of output bytes that can be generated before reseeding has to happen. Impact An application relying on libcrux-hmac-drgb to provide...

RUSTSEC-2026-0227 NIP-44 v2 decryption permits resource exhaustion
The NIP-44 decryption entry point Base64-decoded the complete attacker-controlled payload before determining its version or enforcing any size limit. For v2 payloads, the decoded buffer was then authenticated with HMAC even when it was much larger than the maximum payload supported by the crate's...

CVE-2026-53501
Thumbor is an open-source photo thumbnail service by globo.com. Prior to 7.8.0, Thumbor’s HMAC validation can be bypassed due to the use of Python’s .replace when removing the signature from the URL before validation. Since .replace removes all occurrences of the substring, an attacker can insert...

CVE-2026-53501
Thumbor (open-source image thumbnail service by globo.com) is affected prior to version 7.8.0. The vulnerability stems from using Python’s .replace() to strip the signature from the URL before HMAC validation, which removes all occurrences of the substring. An attacker can insert the same signatu...
