GHSA-jhm9-h84h-rw83 is a medium-severity (CVSS 5.8) CWE-610 vulnerability in phpbb/phpbb. O3 Security confirms whether GHSA-jhm9-h84h-rw83 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
phpBB Server-Side Request Forgery Vulnerability
Real-World Exposure
phpbb/phpbb🐘phpbb/phpbbReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
A vulnerability exists in phpBB <v3.2.10 and <v3.3.1 which allowed remote image dimensions check to be used to SSRF.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | phpbb/phpbb | ≥ 3.2.0&&< 3.2.10 | 3.2.10 |
| 🐘Packagist | phpbb/phpbb | ≥ 3.3.0&&< 3.3.1 | 3.3.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpbb/phpbb. 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 phpbb/phpbb to 3.2.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jhm9-h84h-rw83 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-jhm9-h84h-rw83 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-jhm9-h84h-rw83. 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-jhm9-h84h-rw83 in your dependencies?
O3 detects GHSA-jhm9-h84h-rw83 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
