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...

CVE-2026-17532

The Seraphinite Accelerator plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'seraphaccelprep' parameter in versions up to, and including, 2.29.15. This is due to the CacheExtractPreparePageParams function using PHP's loose inequality operator != to compare the expecte...

CVE-2026-18568

XML::Sig versions from 0.29 before 0.72 for Perl allow signature verification bypass because verify returns true when every signature was skipped before any cryptographic check. verify in lib/XML/Sig.pm counts the //dsig:Signature elements into $numsigs and iterates over them, but two paths reach...

CVE-2026-18568

XML::Sig for Perl versions prior to 0.72 is vulnerable: verify() can return true without performing any digest or signature checks when multiple signatures are present or id_attr mismatch occurs, effectively bypassing signature verification. Affected range includes 0.29–0.71 (up to 0.28 is not af...

github.com/sigstore/sigstore-go: sigstore-go: Signature bypass allows acceptance of bundles signed with expired keys

A flaw was found in sigstore-go, a software library used for verifying digital signatures. This vulnerability specifically affects the workflow for self-managed long-lived signing keys that do not use certificates. An attacker who possesses an expired signing key can exploit this by creating and...

CVE-2026-13597

The 微信二维码登陆 WordPress plugin through 1.3 does not properly validate WeChat webhook requests, as its signature check always passes, and it discloses the generated login code in the webhook response. This allows an unauthenticated attacker to forge a login event for any existing username, read the...

CVE-2026-13089

OIDC::Lite for Perl up to 0.12.1 is vulnerable to ID Token signature verification bypass via an unpinned algorithm allowlist. If the caller does not pin the alg, verify uses the token header alg and passes it to decode_jwt with an allowlist from the untrusted token, allowing tokens with alg: none...
