GHSA-m738-3rc4-5xv3
LOWGHSA-m738-3rc4-5xv3 is a low-severity (CVSS 2) CWE-693 vulnerability in org.xwiki.platform:xwiki-platform-security-authentication-script. O3 Security confirms whether GHSA-m738-3rc4-5xv3 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
A user without PR can reset user authentication failures information
Real-World Exposure
org.xwiki.platform:xwiki-platform-security-authentication-script☕org.xwiki.platform:xwiki-platform-security-authentication-scriptReal-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 service method used to reset the authentication failures record can be executed by any user with Script rights and does not require Programming rights as it should have. Note that being able to reset the authentication failure record mean that an attacker with script right might use it to try performing a bruteforce attack since she'd been able to virtually deactivate the mechanism introduced to mitigate those attacks.
Patches
The problem has been patched in version 12.6.8, 12.10.4 and 13.0.
Workarounds
There's no workaround besides upgrading and being careful on which user should have Script right access. Note that any bruteforce attack on the authentication should be visible in the logs since the authentication failures are logged.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-security-authentication-script. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update org.xwiki.platform:xwiki-platform-security-authentication-script to 12.6.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m738-3rc4-5xv3 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-m738-3rc4-5xv3 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-m738-3rc4-5xv3. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m738-3rc4-5xv3 in your dependencies?
O3 detects GHSA-m738-3rc4-5xv3 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
