An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-14273 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/mattermost/mattermost/server/v8 (Go): affected all versions; fixed in 8.0.0-20251121122154-b57c297c6d7a\n- github.com/mattermost/mattermost/server/v8 (Go): affected all versions; fixed in 8.0.0-20251121122154-b57c297c6d7a\n- github.com/mattermost/mattermost/server/v8 (Go): affected all versions; fixed in 8.0.0-20251121122154-b57c297c6d7a\n- github.com/mattermost/mattermost-plugin-jira (Go): affected all versions; no fix listed\n- github.com/mattermost/mattermost-plugin-jira (Go): affected all versions; fixed in 4.4.1\n- github.com/mattermost/mattermost-plugin-jira (Go): affected all versions; fixed in 4.4.1\n- github.com/mattermost/mattermost-server (Go): affected all versions; no fix listed\n- github.com/mattermost/mattermost-server/v5 (Go): affected all versions; no fix listed\n- github.com/mattermost/mattermost-server/v6 (Go): affected all versions; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-14273/ (Markdown: https://insights.sbomify.com/CVE-2025-14273/index.md)","id":"CVE-2025-14273","markdown":"https://insights.sbomify.com/CVE-2025-14273/index.md","name":"CVE-2025-14273","record":{"aliases":["GHSA-qvmc-92vg-6r35","GO-2026-4275"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Mattermost Jira plugin","requires_auth":"none","summary":"Unauthenticated attackers can spoof user IDs to issue arbitrary Jira requests via the Mattermost Jira plugin, bypassing authentication and path restrictions.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost_server","vendor":"mattermost"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-303","name":"Incorrect Implementation of Authentication Algorithm"}],"description":"Mattermost versions 11.1.x \u003c= 11.1.0, 11.0.x \u003c= 11.0.5, 10.12.x \u003c= 10.12.3, 10.11.x \u003c= 10.11.7 with the Jira plugin enabled and Mattermost Jira plugin versions \u003c=4.4.0 fail to enforce authentication and issue-key path restrictions in the Jira plugin, which allows an unauthenticated attacker who knows a valid user ID to issue authenticated GET and POST requests to the Jira server via crafted plugin payloads that spoof the user ID and inject arbitrary issue key paths.
