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-2025-54478 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/mattermost/mattermost-plugin-confluence (Go): affected all versions; fixed in 1.5.0\n- github.com/mattermost/mattermost-plugin-confluence (Go): affected all versions; fixed in 1.5.0\n- github.com/mattermost/mattermost-plugin-confluence (Go): affected all versions; fixed in 1.5.0\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-2025-54478/ (Markdown: https://insights.sbomify.com/CVE-2025-54478/index.md)","id":"CVE-2025-54478","markdown":"https://insights.sbomify.com/CVE-2025-54478/index.md","name":"CVE-2025-54478","record":{"aliases":["GHSA-qpjq-c5hr-7925","GO-2025-3875"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Mattermost Confluence Plugin","requires_auth":"none","summary":"Unauthenticated attackers can edit channel subscriptions in the Mattermost Confluence Plugin due to missing authentication checks on the API endpoint.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"confluence","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:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Mattermost Confluence Plugin version \u003c1.5.0 fails to enforce authentication of the user to the Mattermost instance which allows unauthenticated attackers to edit channel subscriptions via API call to the edit channel subscription endpoint.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Unauthenticated Channel Subscription Edit in Mattermost Confluence Plugin","id":"CVE-2025-54478","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2025"},"n_packages":3,"n_references":1,"next":{"headline":"BIG-IP PEM vulnerability","id":"CVE-2025-54479"},"packages":[{"ecosystem":"Go","fixed":["1.5.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mattermost/mattermost-plugin-confluence","purl":null,"source":"GHSA-qpjq-c5hr-7925"},{"ecosystem":"Go","fixed":["1.5.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mattermost/mattermost-plugin-confluence","purl":"pkg:golang/github.com/mattermost/mattermost-plugin-confluence","source":"GHSA-qpjq-c5hr-7925"},{"ecosystem":"Go","fixed":["1.5.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mattermost/mattermost-plugin-confluence","purl":"pkg:golang/github.com/mattermost/mattermost-plugin-confluence","source":"GO-2025-3875"}],"prev":{"headline":"Joomla!
