Which packages are affected by GHSA-vjv6-gq77-3mjw?

GHSA-vjv6-gq77-3mjw affects the following packages: org.mapfish.print:print-lib (Maven), org.mapfish.print:print-servlet (Maven), org.mapfish.print:print-standalone (Maven). Ecosystems affected: Maven.

How do I fix GHSA-vjv6-gq77-3mjw?

Update org.mapfish.print:print-lib to 3.24 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vjv6-gq77-3mjw is resolved across your whole dependency graph.

How do I detect GHSA-vjv6-gq77-3mjw in my Maven dependencies?

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

How do I mitigate GHSA-vjv6-gq77-3mjw 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-vjv6-gq77-3mjw actively exploited in the wild?

No public exploit code has been indexed for GHSA-vjv6-gq77-3mjw 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-vjv6-gq77-3mjw?

GHSA-vjv6-gq77-3mjw has an EPSS (Exploit Prediction Scoring System) score of 1.3%, placing it in the 72th 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-vjv6-gq77-3mjw?
