GHSA-cf9m-q836-vf26
HIGHGHSA-cf9m-q836-vf26 is a high-severity (CVSS 7.5) Information Exposure vulnerability in swift. O3 Security confirms whether GHSA-cf9m-q836-vf26 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenStack Swift Discloses Secret URLs to Timing Attack
Blast Radius
swift🐍swift🐍swiftReal-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
The TempURL middleware in OpenStack Object Storage (Swift) 1.4.6 through 1.8.0, 1.9.0 through 1.10.0, and 1.11.0 allows remote attackers to obtain secret URLs by leveraging an object name and a timing side-channel attack.
Affected Packages

| 🐍PyPI | swift | ≥ 1.4.6 | No fix |
| 🐍PyPI | swift | ≥ 1.9.0 | No fix |
| 🐍PyPI | swift | ≥ 1.11.0&&< 1.12.0 | 1.12.0 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for swift. 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
No patched version of swift has shipped for GHSA-cf9m-q836-vf26 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
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-cf9m-q836-vf26 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-cf9m-q836-vf26. 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-cf9m-q836-vf26 in your dependencies?
O3 detects GHSA-cf9m-q836-vf26 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
