# CVE-2024-47806: Jenkins OpenId Connect Authentication Plugin lacks audience claim validation

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 50: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 50% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.jenkins-ci.plugins:oic-auth (Maven) < 4.355.v3a, fixed in 4.355.v3a . Check your lockfile, including transitive dependencies.

## What it is

Jenkins OpenId Connect Authentication Plugin 4.354.v321ce67a1de8 and earlier does not check the aud (Audience) claim of an ID Token, allowing attackers to subvert the authentication flow, potentially gaining administrator access to Jenkins.

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
