MinIO - Incomplete Signature Validation for Unsigned-Trailer Uploads
MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. The signature component of the authorization may be invalid, which would mean that as a client you can use any arbitrary secret to upload objects given the user already has prior WRITE permissions on...

PyJWT is a JSON Web Token implementation in Python. From 2.9.0 to 2.12.1, there is a verifier-side algorithm allow-list bypass when jwt.decode or jwt.decode complete are called with a PyJWK key. The token header alg is checked against the caller-supplied algorithms allow-list, but signature...

Fedify has an LD-Signature Bypass via JSON-LD Named-Graph Restructuring
Summary An attacker can make use of JSON-LD features to restructure a JSON-LD document that would change how Fedify interprets it without changing its Linked Data Signature, allowing them to alter a third-party signed activity they have received. Details The vulnerability essentially boils down t...

CVE-2026-44900
CVE-2026-44900 affects epa4all-client (Java client for epa4all / ePA 3.0). The root cause is in SignedPublicKeysTrustValidatorImpl.isTrusted(): the ECDSA verification step discards the boolean result from Signature.verify(), performing certificate chain validation, OCSP check, and signature algor...
CVE-2026-44900 epa4all-client: VAU Signature bypass
epa4all-client is the Java Client for epa4all / ePA 3.0 in the Telematik Infrastruktur. Prior to 1.2.1, in SignedPublicKeysTrustValidatorImpl.isTrusted, the ECDSA signature verification at line 45 discards the boolean return value of Signature.verify. The method performs certificate chain...

Astra Linux - уязвимость в samba
A flaw was discovered in the way Samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request and chose to fragment it, an attacker could replace the later fragments with their own data, thereby bypassing the signature requirements...

bouncycastle: BC-JAVA: PKIX draft CompositeVerifier accepts empty signature sequence as valid
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpkix. The PKIX draft CompositeVerifier implementation improperly accepts an empty signature sequence as a valid cryptographic signature. This issue allows a remote attacker to bypass signature verification mechanisms, potentially...
