Seraphinite Accelerator <= 2.29.18 - Cross-Site Scripting

The Seraphinite Accelerator plugin for WordPress up to and including 2.29.18 was vulnerable to reflected cross-site scripting through the seraphaccelprep parameter. CacheExtractPreparePageParams compared the expected HMAC against the JSON-decoded nonce with PHP's loose != operator, so a JSON...

CVE-2026-75870

Punk versions before 0.18 for Perl allow session cookie forgery via an empty default HMAC key when a session is declared without a secret. The session keyword freezes its options onto the application as given: it does not require a secret, warn, or refuse to start when one is absent. The cookie...

CVE-2026-75870

Punk is a Perl web framework. Versions before 0.18 are vulnerable to session cookie forgery due to an empty default HMAC key when a session is declared without a secret. The session keyword does not require, warn about, or refuse to start when a secret is absent, so both cookie read and write-bac...

UBUNTU-CVE-2026-68554

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.15.0, an on-path attacker can append attributes after MESSAGE-INTEGRITY to an authenticated STUN request on plain UDP or TCP, adjust the STUN header length, and recompute the unkeyed FINGERPRINT while the original HMA...

CVE-2025-30156

A flaw was found in the CephX authentication protocol used by Ceph, a distributed storage system. CephX uses AES-128-CBC encryption with a hardcoded initialization vector and no message authentication HMAC, making it vulnerable to the same class of unauthenticated-encryption attacks that...

CVE-2026-68554 Coturn: STUN attributes after MESSAGE-INTEGRITY are processed, letting on-path attackers modify authenticated TURN requests

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.15.0, an on-path attacker can append attributes after MESSAGE-INTEGRITY to an authenticated STUN request on plain UDP or TCP, adjust the STUN header length, and recompute the unkeyed FINGERPRINT while the original HMA...

CVE-2026-68554

Coturn (open-source TURN/STUN server) prior to 4.15.0 is vulnerable to an on-path STUN message truncation attack. The root cause is that the server-side parser in src/server/ns_turn_server.c continues processing attributes after the MESSAGE-INTEGRITY field. Since the HMAC covers only the message ...

CVE-2026-49423

In FreeBSD's KTLS receive path, ktls_ocf_tls_cbc_decrypt() incremented the iovec index for every mbuf, including skipped header-only ones, leaving uninitialized entries that caused a kernel panic during HMAC computation. A remote TLS peer controlling TCP segmentation triggers this. Workaround: se...
