Unauthenticated WordPress core flaw forces urgent updates across 6.9/7.0 lines

An anonymous HTTP request can trigger remote code execution in WordPress core on affected 6.9.x and 7.0.x releases via the REST batch endpoint. WordPress patched 6.9.5 and 7.0.2 on July 17, 2026, after auto-updates began rolling out, but some sites may still be vulnerable if they didn’t receive the update. Mitigations before updating include blocking the batch endpoints at /wp-json/batch/v1 and rest_route=/batch/v1, disabling the REST API, or using a drop-in to filter anonymous batch requests. There is no CVE yet, and a tester at wp2shell.com lets site owners check exposure. The exact number of affected sites is unclear, though the vulnerable window covers recent WordPress releases only.

Public PoC Reveals Critical libssh2 Pre-Auth Bug (CVE-2026-55200)

A public proof-of-concept exposes a critical pre-auth memory-corruption flaw in libssh2 (CVE-2026-55200) that can trigger code execution when a client connects to a malicious SSH server; affects all releases up to 1.11.1 with a CVSS of 9.2. No fixed release exists yet; the patch is in mainline and backports are underway (e.g., Debian testing). Inventory every usage of libssh2, including static or bundled copies, and apply a build containing commit 97acf3d. Until patched, restrict outbound SSH, verify host keys, and monitor for oversized-packet anomalies. Related issues CVE-2026-55199 and CVE-2025-15661 are also noted; exploitation in the wild has not been observed.
