Which packages are affected by GHSA-95f9-94vc-665h?

GHSA-95f9-94vc-665h affects the following packages: github.com/beego/beego (Go), github.com/beego/beego/v2 (Go). Ecosystems affected: Go.

How do I fix GHSA-95f9-94vc-665h?

Update github.com/beego/beego to 1.12.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-95f9-94vc-665h is resolved across your whole dependency graph.

How do I detect GHSA-95f9-94vc-665h in my Go dependencies?

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

How do I mitigate GHSA-95f9-94vc-665h if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is GHSA-95f9-94vc-665h actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-95f9-94vc-665h, including 1 in-the-wild exploitation 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 is the EPSS score for GHSA-95f9-94vc-665h?

GHSA-95f9-94vc-665h has an EPSS (Exploit Prediction Scoring System) score of 1.7%, placing it in the 77th 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.
