GHSA-mpf5-3vph-q75r
MEDIUMGHSA-mpf5-3vph-q75r is a medium-severity (CVSS 4.3) CWE-862 vulnerability in weblate. O3 Security confirms whether GHSA-mpf5-3vph-q75r is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Weblate: Improper access control for the translation memory in API
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
weblateReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The translation memory API exposed unintended endpoints, which in turn didn't do proper access control.
Patches
Workarounds
Blocking access to /api/memory/ in the HTTP server removes access to this feature.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for weblate. 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 weblate to 5.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mpf5-3vph-q75r 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-mpf5-3vph-q75r 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-mpf5-3vph-q75r. 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-mpf5-3vph-q75r in your dependencies?
O3 detects GHSA-mpf5-3vph-q75r across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
