CVE-2026-92139: Vulnerability in Jenkins Project Jenkins Bitbucket Push and Pull Request Plugin
Jenkins Bitbucket Push and Pull Request Plugin 4.0.1 and earlier trusts values provided in the webhook payload, including certain URLs, and uses configured Bitbucket credentials to connect to those URLs, allowing attackers to capture Bitbucket credentials stored in Jenkins by sending a crafted webhook payload.
AI Analysis
Technical Summary
Jenkins Bitbucket Push and Pull Request Plugin versions up to and including 4.0.1 improperly trust values provided in webhook payloads, including URLs. This trust enables an attacker to craft a malicious webhook payload that causes the plugin to use stored Bitbucket credentials to connect to attacker-controlled URLs, thereby exposing those credentials.
Potential Impact
An attacker who can send a crafted webhook payload to the vulnerable Jenkins plugin can capture Bitbucket credentials stored in Jenkins. This could lead to unauthorized access to Bitbucket repositories and potentially further compromise of the development environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict webhook sources to trusted entities and monitor webhook configurations carefully to prevent malicious payloads.
