Where this sits among everything scored
Real-World Exposure
github.com/revel/revelReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Unsanitized input in the query parser in github.com/revel/revel before v1.0.0 allows remote attackers to cause resource exhaustion via memory allocation.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/revel/revel, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/revel/revel to 1.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hggr-p7v6-73p5 is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
