Which packages are affected by GHSA-jq7p-26h5-w78r?

GHSA-jq7p-26h5-w78r affects the following packages: github.com/apache/thrift (Go). Ecosystems affected: Go.

How do I fix GHSA-jq7p-26h5-w78r?

Update github.com/apache/thrift to 0.13.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jq7p-26h5-w78r is resolved across your whole dependency graph.

How do I detect GHSA-jq7p-26h5-w78r in my Go dependencies?

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

How do I mitigate GHSA-jq7p-26h5-w78r if there is no patch (or I can't update yet)?

Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Is GHSA-jq7p-26h5-w78r actively exploited in the wild?

No public exploit code has been indexed for GHSA-jq7p-26h5-w78r 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-jq7p-26h5-w78r?

GHSA-jq7p-26h5-w78r has an EPSS (Exploit Prediction Scoring System) score of 6.5%, placing it in the 94th 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-jq7p-26h5-w78r?

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatModerate

Red Hat OpenStack Platform ships OpenDaylight, which contains a vulnerable version of libthrift. However, OpenDaylight is not affected as this is a Golang specific problem, lowering the impact of the vulnerability for OpenDaylight. As such, Red Hat will not be providing a fix for OpenDaylight at this time. The version…
