CVE-2026-22703

Cosign provides code signing and transparency for containers and binaries. Prior to versions 2.6.2 and 3.0.4, Cosign bundle can be crafted to successfully verify an artifact even if the embedded Rekor entry does not reference the artifact's digest, signature or public key. When verifying a Rekor...

CVE-2026-22705 RustCrypto: Signatures has timing side-channel in ML-DSA decomposition

RustCrypto: Signatures offers support for digital signatures, which provide authentication of data using public-key cryptography. Prior to version 0.1.0-rc.2, a timing side-channel was discovered in the Decompose algorithm which is used during ML-DSA signing to generate hints for the signature...

CVE-2026-22703 Cosign verification accepts any valid Rekor entry under certain conditions

Cosign provides code signing and transparency for containers and binaries. Prior to versions 2.6.2 and 3.0.4, Cosign bundle can be crafted to successfully verify an artifact even if the embedded Rekor entry does not reference the artifact's digest, signature or public key.

CVE-2026-22703

Cosign prior to versions 2.6.2 and 3.0.4 could verify a Rekor entry without actually checking the artifact digest, signature, or public key, allowing a malicious actor to craft a valid bundle from any Rekor entry and evade audit. The issue affects Cosign’s signing/verification workflow and could ...

QES-Backed Virtual FIDO2 Authenticators: Architectural Options for Secure, Synchronizable WebAuthn Credentials

FIDO2 and the WebAuthn standard offer phishing-resistant, public-key based authentication but traditionally rely on device-bound cryptographic keys that are not naturally portable across user devices. Recent passkey deployments address this limitation by enabling multi-device credentials...

jose-swift has JWT Signature Verification Bypass via None Algorithm

Summary An authentication bypass vulnerability allows any unauthenticated attacker to forge arbitrary JWT tokens by setting "alg": "none" in the token header. The library's verification functions immediately return true for such tokens without performing any cryptographic verification, enabling...

CVE-2023-25718

In ConnectWise Control through 22.9.10032 formerly known as ScreenConnect, after an executable file is signed, additional instructions can be added without invalidating the signature, such as instructions that result in offering the end user a different attacker-controlled executable file. It is...

CVE-2023-40090

In BTMBleVerifySignature of btmble.cc, there is a possible way to bypass signature validation due to side channel information disclosure. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...

CVE-2018-12434

LibreSSL before 2.6.5 and 2.7.x before 2.7.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical ho...

CVE-2018-18688

The Portable Document Format PDF specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or...

CVE-2021-0152

Improper verification of cryptographic signature in the installer for some IntelR Wireless BluetoothR and KillerTM BluetoothR products in Windows 10 may allow an authenticated user to potentially enable denial of service via local access...

CVE-2025-40934

XML-Sig versions 0.27 through 0.67 for Perl incorrectly validates XML files if signatures are omitted. An attacker can remove the signature from the XML document to make it pass the verification check. XML-Sig is a Perl module to validate signatures on XML files. An unsigned XML file should retur...

CVE-2022-23334

The Robot application in Ip-label Newtest before v8.5R0 was discovered to use weak signature checks on executed binaries, allowing attackers to have write access and escalate privileges via replacing NEWTESTREMOTEMANAGER.EXE...
