openssl: CMS AuthEnvelopedData Processing May Accept Forged Messages

A flaw was found in OpenSSL's Cryptographic Message Services CMS AuthEnvelopedData processing. An on-path attacker can exploit insufficient input validation on cipher and tag length fields by sending specially crafted CMS messages. This can lead to the forging of messages or bypassing integrity...

CVE-2026-18152

IBM Financial Transaction Manager (FTM) for RedHat OpenShift is vulnerable to a flaw where a remote attacker can forge validly-signed messages . This issue stems from the improper verification of cryptographic signatures . The vulnerability has a CVSS 3.1 base score of 7.4 (HIGH) , with an integr...

CVE-2026-18152 IBM Financial Transaction Manager (FTM) is Impacted by Multiple Vulnerabilities

IBM Financial Transaction Manager FTM for RedHat OpenShift could allow a remote attacker to forge validly-signed messages due to improper verification of cryptographic signatures...

GHSA-C3GV-825Q-FVMP libp2p: Gossipsub StrictSign accepts attacker-signed messages as a victim RSA peer ID

Summary @libp2p/gossipsub StrictSign validation does not bind a supplied message public key to the claimed from peer ID when from is an RSA-style peer ID that does not inline its public key. An attacker can set from to a victim RSA peer ID, sign the message with the attacker's own private key,...

CVE-2026-75803

A flaw in OpenSSL causes EVPCipher to skip AEAD tag verification for ChaCha20-Poly1305 and AES-OCB ciphers when decrypting empty ciphertexts. This allows remote attackers to submit forged messages that affected applications incorrectly accept as valid. Mitigation To mitigate this ensure that all...
