Which packages are affected by GHSA-gfgr-6hrj-85ww?

GHSA-gfgr-6hrj-85ww affects the following packages: github.com/juju/juju (Go). Ecosystems affected: Go.

How do I fix GHSA-gfgr-6hrj-85ww?

Update github.com/juju/juju to 3.6.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gfgr-6hrj-85ww is resolved across your whole dependency graph.

How do I detect GHSA-gfgr-6hrj-85ww in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/juju/juju. 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 GHSA-gfgr-6hrj-85ww 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 GHSA-gfgr-6hrj-85ww?

O3 pinpoints whether GHSA-gfgr-6hrj-85ww 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 GHSA-gfgr-6hrj-85ww actively exploited in the wild?

No public exploit code has been indexed for GHSA-gfgr-6hrj-85ww 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-gfgr-6hrj-85ww?

GHSA-gfgr-6hrj-85ww has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 14th 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-gfgr-6hrj-85ww?

GHSA-gfgr-6hrj-85ww is classified as CWE-708 (CWE-708). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Description

A race condition in the secrets management subsystem of Juju versions 3.0.0 through 3.6.18 allows an authenticated unit agent to claim ownership of a newly initialized secret. Between generating a Juju Secret ID and creating the secret's first revision, an attacker authenticated as another unit agent can claim ownership of a known secret. This leads to the attacking unit being able to read the content of the initial secret revision.

Impact

Between generating a Secret ID and creating the secret's first revision, an attacker authenticated as another unit agent can claim ownership of a known secret. This leads to the attacking unit being able to read the content of the initial secret revision.
