# CodeMarine Threat Brief · Sat 31 Oct · Level 3 Elevated - Date: 2026-10-31 - Threat level: 3/5 Elevated - Actively exploited: 2 - Malicious packages: 33 - Web page: https://codemarine.ai/brief/2026-10-31/ Backfilled issue. The level was worked out afterwards with the same points rubric. ## Headline alerts - **WordPress takeover bug drew 63,000 attack attempts in a day** Update WordPress to 7.1.4 now; versions 4.7 through 7.1.3 are affected. - **Ivanti Connect Secure VPN chain exploited for full takeover** Upgrade Ivanti Connect Secure to 25.1.1.3 or 22.8R2.6, which close all three flaws in the chain. ## The short version - If you run a WordPress site, update it to version 7.1.4 today; attackers are already trying to break in during updates. - If your company uses Ivanti VPNs for remote access, ask IT to install Ivanti's latest update straight away. - If you use Cursor with the Claude Code add-on, check its version; anyone who got version 2.1.313 should treat that computer as hacked and change their passwords and keys. - If your apps run on Northflank, change every password and API key stored there now, as the company says all of them may have been exposed. - If your team hosts its own GitLab, make sure it has GitLab's 21 October update or later; the US government says attackers are now using a 10 out of 10 flaw. ## Today's stories ### WordPress update race lets attackers run code Severity: critical A flaw in WordPress Core 4.7 through 7.1.3 (CVSS 8.1) lets an attacker with no login run code on a site during the few seconds a full core update is being unpacked, because the staged files sit in a predictable, web-reachable folder. Wordfence blocked 62,969 attempts in 24 hours, with some attackers polling the same sites for about 14.5 hours to catch the window. Update to 7.1.4 and check for unexpected PHP files under the upgrade folder or unfamiliar admin accounts.

Ivanti says a limited number of customers were hit so far. Upgrade to 25.1.1.3 or 22.8R2.6 and check for signs of compromise from before the patch.

It adds an attacker SSH key labelled svc-telemetry, installs persistence, opens a reverse tunnel and sends host details plus the names of secret-looking environment variables. Open VSX and Microsoft's marketplace were not affected; move to 2.1.314, and on any machine that got 2.1.313, remove the key and persistence and rotate credentials.

Rotate all secrets in workloads, secret groups and global secrets, and turn off public access to databases and other add-ons.

GitLab's fix is 19.4.2, 19.3.5 or 19.2.8, and 19.3.4 is still affected. This is a different flaw from CVE-2026-110264, fixed on 21 October, so the newest release on your branch is the safe choice.

Update to Commerce Core 3.3.13 or 8.x-2.41.
