# CVE-2025-47884: Jenkins OpenID Connect Provider Plugin Incorrectly Validates Crafted Build ID Tokens

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (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.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes io.jenkins.plugins:oidc-provider (Maven) < 111.v29fd614b3617, fixed in 111.v29fd614b_3617 . Check your lockfile, including transitive dependencies.

## What it is

In Jenkins OpenID Connect Provider Plugin 96.vee8ed882ec4d and earlier the generation of build ID Tokens uses potentially overridden values of environment variables, in conjunction with certain other plugins allowing attackers able to configure jobs to craft a build ID Token that impersonates a trusted job, potentially gaining unauthorized access to external services.

## Affected packages

- Maven `io.jenkins.plugins:oidc-provider` < 111.v29fd614b3617 → fixed: 111.v29fd614b_3617

## Affected products (CVE record)

- Jenkins Project Jenkins OpenID Connect Provider Plugin: <= 96.vee8ed882ec4d

## Severity

- CISA-ADP CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:L`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:L`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.64% probability of exploitation activity in the next 30 days; percentile 50.
