GHSA-c3fc-8qff-9hwx affects the following packages: org.bouncycastle:bcprov-jdk14 (Maven), org.bouncycastle:bcprov-jdk15to18 (Maven), org.bouncycastle:bcprov-jdk18on (Maven). Ecosystems affected: Maven.

How do I fix GHSA-c3fc-8qff-9hwx?

Update org.bouncycastle:bcprov-jdk14 to 1.84 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c3fc-8qff-9hwx is resolved across your whole dependency graph.

How do I detect GHSA-c3fc-8qff-9hwx in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.bouncycastle:bcprov-jdk14, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-c3fc-8qff-9hwx 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-c3fc-8qff-9hwx?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-c3fc-8qff-9hwx can be triaged on real exposure rather than presence alone.

Is GHSA-c3fc-8qff-9hwx actively exploited in the wild?

No public exploit code has been indexed for GHSA-c3fc-8qff-9hwx 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-c3fc-8qff-9hwx?

GHSA-c3fc-8qff-9hwx has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 44th 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-c3fc-8qff-9hwx?

GHSA-c3fc-8qff-9hwx is classified as CWE-90 (CWE-90). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-c3fc-8qff-9hwx published, and has it been updated?

GHSA-c3fc-8qff-9hwx was published on April 17, 2026 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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 HatImportant

To exploit this issue, an attacker needs to submit crafted input to an application using the `LDAPStoreHelper` implementation for directory queries. An attack typically requires the application to pass the malicious input directly into a search filter, allowing the attacker to modify the resulting LDAP query. The…
