GHSA-58qw-9mgm-455v
Fix: pypa/pip#13870GHSA-58qw-9mgm-455v is a security vulnerability in pip. O3 Security confirms whether GHSA-58qw-9mgm-455v is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
pip has an interpretation conflict due to handling both concatenated tar and ZIP files as ZIP files
Real-World Exposure
pipReal-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
pip handles concatenated tar and ZIP files as ZIP files regardless of filename or whether a file is both a tar and ZIP file. This behavior could result in confusing installation behavior, such as installing "incorrect" files according to the filename of the archive. New behavior only proceeds with installation if the file identifies uniquely as a ZIP or tar archive, not as both.
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 pip. 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 pip to 26.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-58qw-9mgm-455v 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-58qw-9mgm-455v 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-58qw-9mgm-455v. 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-58qw-9mgm-455v in your dependencies?
O3 detects GHSA-58qw-9mgm-455v across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
