Severity by source
AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
Network-reachable and low-complexity, but PR:L because the attacker must control build log content (job run/configure); C raised to H because a reusable Develocity credential is captured, with no integrity or availability impact.

Jenkins Gradle Plugin 2.19.1252.v15196b_5a_6e10 and earlier requests build scan data from the build scan link detected in the build log, even when a Develocity server URL is configured in the global configuration, allowing attackers able to control the build log to capture the Develocity access key configured in the global configuration by having Jenkins connect to an attacker-specified URL.
AnalysisAI
Information disclosure in Jenkins Gradle Plugin 2.19.1252.v15196b_5a_6e10 and earlier lets an authenticated Jenkins user who can influence the build log of a Gradle job trick the plugin into fetching build scan data from an attacker-controlled URL in preference to the Develocity server URL set in the plugin's global configuration. Because the plugin attaches the globally configured Develocity access key to that outbound request, the attacker can capture the credential; instances with no Develocity access key configured have nothing to leak, so exposure is conditional rather than universal. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires (1) an authenticated Jenkins user with the ability to control build log content - i.e., permission to run or configure a Gradle job whose output the plugin parses - and (2) a Develocity access key actually configured in the plugin's global configuration, since that key is the target of the leak. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but moderate-severity issue, not an urgent priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade the Jenkins Gradle Plugin to a release newer than 2.19.1252.v15196b_5a_6e10 as specified in the Jenkins security advisory https://www.jenkins.io/security/advisory/2026-09-16/#SECURITY-4028; because the exact fixed version is not stated in the supplied data, confirm the patched plugin version from that advisory before upgrading, and note that plugin updates on a Jenkins controller require a restart or plugin reload, which briefly interrupts build scheduling. … Detailed patch versions, workarounds, and compensating controls in full report. |
