CVE-2022-31038: XSS vulnerability in repository issue list in Gogs

Gogs is an open source self-hosted Git service. In versions of gogs prior to 0.12.9 `DisplayName` does not filter characters input from users, which leads to an XSS vulnerability when directly displayed in the issue list. This issue has been resolved in commit 155cae1d which sanitizes `DisplayName` prior to display to the user. All users of gogs are advised to upgrade. Users unable to upgrade should check their users' display names for malicious characters.

Security readout for executives and security teams

Plain-English summary

CVE-2022-31038 is a stored cross-site scripting flaw in Gogs before 0.12.9. A user-controlled display name can appear unsanitized in repository issue lists, allowing script execution in another user's browser when that list is viewed. Business impact is limited but relevant for self-hosted code platforms.

Executive priority

Treat as a moderate-priority fix for any internet-facing or multi-user Gogs deployment. Prioritize upgrade during normal patch windows unless the instance allows untrusted users.

Technical view

Gogs versions before 0.12.9 fail to filter DisplayName before rendering it in the repository issue list. The advisory maps this to CWE-79 with CVSS 3.1 score 5.4, requiring network access, low privileges, and user interaction. The fix sanitizes DisplayName before display.

Likely exposure

Exposure is limited to organizations running self-hosted Gogs versions earlier than 0.12.9, especially instances allowing untrusted or broad user registration.

Exploitation context

The source bundle does not cite active exploitation, and KEV status is false. Exploitation requires a user account and another user viewing an affected issue list.

Researcher notes

The evidence identifies the vulnerable sink as issue-list display of DisplayName and the remediation commit as 155cae1d. No exploit proof, active exploitation claim, or additional affected products are provided in the bundle.

Mitigation direction

  • Upgrade Gogs to version 0.12.9 or later.
  • If unable to upgrade, review user display names for malicious characters.
  • Restrict untrusted account creation until upgraded.
  • Monitor vendor advisory and release notes for related guidance.

Validation and detection

  • Inventory all self-hosted Gogs instances and record versions.
  • Confirm no production instance runs Gogs before 0.12.9.
  • Review user display names for unsafe markup-like characters.
  • Confirm issue lists render display names safely after upgrade.
