Description

Multiple cross-site request forgery (CSRF) vulnerabilities in the Admin Console in Fork before 5.8.3 allows remote attackers to perform unauthorized actions as administrator to (1) approve the mass of the user's comments, (2) restoring a deleted user, (3) installing or running modules, (4) resetting the analytics, (5) pinging the mailmotor api, (6) uploading things to the media library, (7) exporting locale.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for forkcms/forkcms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update forkcms/forkcms to 5.8.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-23960 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
