CVE-2024-47877
Fix: codeclysm/extract@4a98568CVE-2024-47877 is a Path Traversal vulnerability in github.com/codeclysm/extract/v3. O3 Security confirms whether CVE-2024-47877 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Extract has insufficient checks allowing attacker to create symlinks outside the extraction directory.
Real-World Exposure

Description
Extract is aA Go library to extract archives in zip, tar.gz or tar.bz2 formats. A maliciously crafted archive may allow an attacker to create a symlink outside the extraction target directory. This vulnerability is fixed in 4.0.0. If you're using the Extractor.FS interface, then upgrading to /v4 will require to implement the new methods that have been added.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/codeclysm/extract/v3. 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 github.com/codeclysm/extract/v3 has shipped for CVE-2024-47877 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 CVE-2024-47877 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 CVE-2024-47877. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
