Description

Silverpeas Core 6.3.1 is vulnerable to Incorrect Access Control. An attacker with low privileges is able to execute the administrator-only function of putting the application in "Maintenance Mode" due to broken access control. This makes the application unavailable to all users. This affects Silverpeas Core 6.3.1 and below.

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update org.silverpeas.core:silverpeas-core-war to 6.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-whgv-6j78-5rh2 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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-whgv-6j78-5rh2 can be triaged on real exposure rather than presence alone.

Tailored to GHSA-whgv-6j78-5rh2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
