# CVE-2025-32972: The lesscss script service allows cache clearing without programming right > Attackers with script rights can clear the LESS compiler cache without programming rights, causing performance degradation in XWiki. - **Severity:** Low 2.7 (`CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L`) - **Exploited in the wild:** Not known - **Login needed:** An administrator - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 30 Apr 2025 - **Updated:** 30 Apr 2025 - **Also known as:** GHSA-rp38-24m3-rx87 ## What is CVE-2025-32972? CVE-2025-32972 is a low-severity missing authorization vulnerability in Xwiki Xwiki, published on 30 Apr 2025. An attacker needs administrator access to exploit it, with no action from the victim. ### Official description XWiki is a generic wiki platform. In versions starting from 6.1-milestone-1 to before 15.10.12, from 16.0.0-rc-1 to before 16.4.3, and from 16.5.0-rc-1 to before 16.8.0-rc-1, the script API of the LESS compiler in XWiki is incorrectly checking for rights when calling the cache cleaning API, making it possible to clean the cache without having programming right. The only impact of this is a slowdown in XWiki execution as the caches are re-filled. As this vulnerability requires script right to exploit, and script right already allows unlimited execution of scripts, the additional impact due to this vulnerability is low. This issue has been patched in versions 15.10.12, 16.4.3, and 16.8.0-rc-1.

Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
