Which packages are affected by CVE-2024-3094?

Affected package information for CVE-2024-3094 is not yet fully mapped. Check the official advisory links for details.

How do I fix CVE-2024-3094?

No patched version of the affected component has shipped for CVE-2024-3094 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-2024-3094 in my code and dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. 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-2024-3094 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-2024-3094?

O3 pinpoints whether CVE-2024-3094 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-2024-3094 actively exploited in the wild?

Yes. There are 45 known exploit references for CVE-2024-3094, including 22 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What type of vulnerability is CVE-2024-3094?

CVE-2024-3094 is classified as CWE-506 (CWE-506). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2024-3094 published, and has it been updated?

CVE-2024-3094 was published on March 29, 2024 and was last updated on July 15, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

CVE-2024-3094

CRITICAL

CVE-2024-3094 is a critical-severity (CVSS 10) CWE-506 vulnerability. 45 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2024-3094 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

Malicious code was discovered in the upstream tarballs of xz, starting with version 5.6.0. Through a series of complex obfuscations, the liblzma build process extracts a prebuilt object file from a disguised test file existing in the source code, which is then used to modify specific functions in the liblzma code. This results in a modified liblzma library that can be used by any software linked against this library, intercepting and modifying the data interaction with this library.

Exploits & PoCs

Research use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.
