GHSA-r5m4-5vww-w9f5 is a medium-severity (CVSS 5.3) remote code execution vulnerability in gdal. O3 Security confirms whether GHSA-r5m4-5vww-w9f5 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OSGeo gdal has a heap-based buffer overflow
Real-World Exposure
gdalReal-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
A flaw has been found in OSGeo gdal up to 3.13.0dev-4. Affected by this vulnerability is the function SWSDfldsrch of the file frmts/hdf4/hdf-eos/SWapi.c. Executing a manipulation can lead to heap-based buffer overflow. The attack requires local access. The exploit has been published and may be used. Upgrading to version 3.13.0RC1 addresses this issue. This patch commit sha is 3e04c0385630e4d42517046d9a4967dfccfeb7fd. The affected component should be upgraded.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for gdal. 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 gdal to 3.13.0RC1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r5m4-5vww-w9f5 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-r5m4-5vww-w9f5 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-r5m4-5vww-w9f5. 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-r5m4-5vww-w9f5 in your dependencies?
O3 detects GHSA-r5m4-5vww-w9f5 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
