CVE-2024-52594 has a CVSS score of 4.3/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2024-52594?

CVE-2024-52594 affects the following packages: github.com/matrix-org/gomatrixserverlib (Go). Ecosystems affected: Go.

How do I fix CVE-2024-52594?

Update github.com/matrix-org/gomatrixserverlib to 0.0.0-20250116181547-c4f1e01eab0d or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-52594 is resolved across your whole dependency graph.

How do I detect CVE-2024-52594 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/matrix-org/gomatrixserverlib. 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-2024-52594 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-2024-52594?

O3 pinpoints whether CVE-2024-52594 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-2024-52594 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-52594 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-2024-52594?

CVE-2024-52594 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 25th 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-2024-52594?

CVE-2024-52594 is classified as Server-Side Request Forgery (SSRF) (CWE-918). This weakness type 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-2024-52594 published, and has it been updated?

CVE-2024-52594 was published on January 16, 2025 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

Gomatrixserverlib is a Go library for matrix federation. Gomatrixserverlib is vulnerable to server-side request forgery, serving content from a private network it can access, under certain conditions. The commit c4f1e01 fixes this issue. Users are advised to upgrade. Users unable to upgrade should use a local firewall to limit the network segments and hosts the service using gomatrixserverlib can access.
