GHSA-49w7-5r33-jm9m
MEDIUMhttp-swagger XSS via PUT requests
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
github.com/swaggo/http-swaggerReal-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
http-swagger before 1.2.6 allows XSS via PUT requests, because a file that has been uploaded (via httpSwagger.WrapHandler and *webdav.memFile) can subsequently be accessed via a GET request. NOTE: this is independently fixable with respect to CVE-2022-24863, because (if a solution continued to allow PUT requests) large files could have been blocked without blocking JavaScript, or JavaScript could have been blocked without blocking large files.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/swaggo/http-swagger. 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 github.com/swaggo/http-swagger to 1.2.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-49w7-5r33-jm9m 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-49w7-5r33-jm9m 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-49w7-5r33-jm9m. 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-49w7-5r33-jm9m in your dependencies?
O3 detects GHSA-49w7-5r33-jm9m across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
