MEDIUM

GHSA-r6jg-jfv6-2fjv is a medium-severity (CVSS 5) Server-Side Request Forgery (SSRF) vulnerability in github.com/t2bot/matrix-media-repo. O3 Security confirms whether GHSA-r6jg-jfv6-2fjv is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

Impact

Matrix Media Repo (MMR) is vulnerable to server-side request forgery, serving content from a private network it can access, under certain conditions.

Patches

This is fixed in MMR v1.3.8.

Workarounds

Restricting which hosts MMR is allowed to contact via (local) firewall rules or a transparent proxy.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/t2bot/matrix-media-repo. 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.

  2. Fix

    Update github.com/t2bot/matrix-media-repo to 1.3.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r6jg-jfv6-2fjv is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-r6jg-jfv6-2fjv 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-r6jg-jfv6-2fjv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
