CVE-2024-47877 affects the following packages: github.com/codeclysm/extract/v3 (Go), github.com/codeclysm/extract/v4 (Go), github.com/codeclysm/extract (Go). Ecosystems affected: Go.

How do I fix CVE-2024-47877?

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.

How do I detect CVE-2024-47877 in my Go dependencies?

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.

How do I mitigate CVE-2024-47877 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2024-47877?

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.

Is CVE-2024-47877 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-47877 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-47877?

CVE-2024-47877 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-47877?

CVE-2024-47877 is classified as Path Traversal (CWE-22), CWE-61 (CWE-61). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2024-47877 published, and has it been updated?

CVE-2024-47877 was published on October 11, 2024 and was last updated on April 2, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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.
