How severe is GHSA-v9gv-xp36-jgj8?

GHSA-v9gv-xp36-jgj8 has a CVSS score of 5.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-v9gv-xp36-jgj8?

GHSA-v9gv-xp36-jgj8 affects the following packages: rabbit_common (Hex), rabbit_common (Hex), rabbit_common (Hex). Ecosystems affected: Hex.

How do I fix GHSA-v9gv-xp36-jgj8?

Update rabbit_common to 3.10.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v9gv-xp36-jgj8 is resolved across your whole dependency graph.

How do I detect GHSA-v9gv-xp36-jgj8 in my Hex dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rabbit_common, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-v9gv-xp36-jgj8 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.

Is GHSA-v9gv-xp36-jgj8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-v9gv-xp36-jgj8 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 GHSA-v9gv-xp36-jgj8?

GHSA-v9gv-xp36-jgj8 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 33th 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 GHSA-v9gv-xp36-jgj8?

GHSA-v9gv-xp36-jgj8 is classified as Insufficient Random Values (CWE-330), CWE-335 (CWE-335). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-v9gv-xp36-jgj8 published, and has it been updated?

GHSA-v9gv-xp36-jgj8 was published on June 30, 2026 and was last updated on June 30, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Hex packages — download data is not available via public APIs for these ecosystems.

Description

Impact

Shovel and Federation plugins perform URI obfuscation in their worker (link) state. The encryption key used to encrypt the URI was seeded with a predictable secret.

This means that in case of certain exceptions related to Shovel and Federation plugins, reasonably easily deobfuscatable data could appear in the node log.

Patched versions correctly use a cluster-wide secret for that purpose.

Patches

Patched versions:

3.10.2
3.9.18
3.8.32

Workarounds

Disable Shovel and Federation plugins.
