GHSA-553q-hpvp-q8pc
HIGHServer-Side Request Forgery in snipe/snipe-it
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
snipe/snipe-itReal-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
Admin users on the external network can perform blind POST-based SSRF (issue requests on behalf of the server into the internal network) via the Slack Integration. This vulnerability is capable of port-scanning of the internal network, issue POST requests to web servers on the internal network which can be escalated to higher-impact.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | snipe/snipe-it | all versions | 6.0.0-GM |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for snipe/snipe-it. 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 snipe/snipe-it to 6.0.0-GM or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-553q-hpvp-q8pc 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-553q-hpvp-q8pc 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-553q-hpvp-q8pc. 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-553q-hpvp-q8pc in your dependencies?
O3 detects GHSA-553q-hpvp-q8pc across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
