CVE-2026-22818

CVE-2026-22818 concerns Hono’s JWK/JWKS JWT verification middleware. Prior to 4.11.4, if a JWK did not explicitly specify an algorithm, the middleware could derive the signature verification algorithm from the untrusted JWT header’s alg value, enabling algorithm confusion and potentially forged t...

CVE-2025-68820 ext4: xattr: fix null pointer deref in ext4_raw_inode()

In the Linux kernel, the following vulnerability has been resolved: ext4: xattr: fix null pointer deref in ext4rawinode If ext4getinodeloc fails e.g. if it returns -EFSCORRUPTED, iloc.bh will remain set to NULL. Since ext4xattrinodedecrefall lacks error checking, this will lead to a null pointer...

GHSA-WHQX-F9J3-CH6M Cosign verification accepts any valid Rekor entry under certain conditions

Impact A 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 entry, Cosign verifies the Rekor entry signature, and also compares the artifact's digest, the user's...
