Which packages are affected by GHSA-rp38-24m3-rx87?

GHSA-rp38-24m3-rx87 affects the following packages: org.xwiki.platform:xwiki-platform-lesscss-script (Maven), org.xwiki.platform:xwiki-platform-lesscss-script (Maven), org.xwiki.platform:xwiki-platform-lesscss-script (Maven). Ecosystems affected: Maven.

How do I fix GHSA-rp38-24m3-rx87?

Update org.xwiki.platform:xwiki-platform-lesscss-script to 15.10.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rp38-24m3-rx87 is resolved across your whole dependency graph.

How do I detect GHSA-rp38-24m3-rx87 in my Maven dependencies?

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

How do I mitigate GHSA-rp38-24m3-rx87 if there is no patch (or I can't update yet)?

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.

Is GHSA-rp38-24m3-rx87 actively exploited in the wild?

No public exploit code has been indexed for GHSA-rp38-24m3-rx87 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-rp38-24m3-rx87?

GHSA-rp38-24m3-rx87 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-rp38-24m3-rx87 published, and has it been updated?

GHSA-rp38-24m3-rx87 was published on April 29, 2025 and was last updated on April 30, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Impact

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.

Patches

This has been patched in XWiki 15.10.12, 16.4.3 and 16.8.0 RC1.

Workarounds

We're not aware of any workaround except for being careful whom to give script right, which is a general recommendation.
