A security flaw has been discovered in GitBucket up to 4.46.1. This affects the function Git.cloneRepository.setURI of the file src/main/scala/gitbucket/core/service/RepositoryCreationService.scala. Performing a manipulation of the argument url results in server-side request forgery. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks. The patch is named 487a9b980f56aa73b6a044b1e86a92eed5043215. To fix this issue, it is recommended to deploy a patch.
AnalysisAI
Server-side request forgery in GitBucket up to version 4.46.1 allows authenticated users to coerce the application server into issuing HTTP requests to arbitrary internal or private network hosts by supplying a crafted URL to the repository creation "clone from existing repository" feature. The flaw resides in Git.cloneRepository.setURI() within RepositoryCreationService.scala, where user-supplied URL input reaches JGit without validation against private address ranges. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated user account on the target GitBucket instance (CVSS PR:L confirmed). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.3 (Medium) accurately reflects the constrained impact: PR:L requires an authenticated user account, and the VC/VI/VA metrics are all Low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated GitBucket user navigates to the 'Create Repository' page and selects the 'Clone from existing repository' initialization option, supplying a crafted source URL such as `http://169.254.169.254/latest/meta-data/` (AWS IMDSv1 endpoint). GitBucket's server-side JGit clone routine issues an HTTP GET to that internal address on behalf of the attacker, and any error messages or partial responses may leak internal service data. … |
| Remediation | Apply the upstream patch commit 487a9b980f56aa73b6a044b1e86a92eed5043215 from PR #4056 (https://github.com/gitbucket/gitbucket/pull/4056); a specific released version incorporating this fix is not independently confirmed - verify against the official GitBucket release page. … Detailed patch versions, workarounds, and compensating controls in full report. |
