Mattermost Jira Plugin vulnerable to Cross-Site Request Forgery

CVE-2024-23319GHSA-4fp6-574p-fc35

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/mattermost/mattermost-plugin-jira 1.1.2-0.20230830170046-f4cf4c6de017), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2024-23319

Advisory: Mattermost Jira Plugin vulnerable to Cross-Site Request Forgery
IDs: CVE-2024-23319, GHSA-4fp6-574p-fc35
Record: https://patchnext.com/advisories/cve-2024-23319 (revision 1, source checked 26 Oct 2026, 15:03 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/mattermost/mattermost-plugin-jira 1.1.2-0.20230830170046-f4cf4c6de017. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/mattermost/mattermost-plugin-jira: affected < 1.1.2-0.20230830170046-f4cf4c6de017; fixed in 1.1.2-0.20230830170046-f4cf4c6de017

## Suggested inspection (read-only)
- Go github.com/mattermost/mattermost-plugin-jira: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/mattermost/mattermost-plugin-jira.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
