An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-39202 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- matrix-appservice-irc (npm): affected all versions; fixed in 0.35.0\n- matrix-appservice-irc (npm): affected all versions; fixed in 0.35.0\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-2022-39202/ (Markdown: https://insights.sbomify.com/CVE-2022-39202/index.md)","id":"CVE-2022-39202","markdown":"https://insights.sbomify.com/CVE-2022-39202/index.md","name":"CVE-2022-39202","record":{"aliases":["GHSA-cq7q-5c67-w39w"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Matrix IRC bridge","requires_auth":"high_privilege","summary":"Incorrect parsing of IRC mode commands allows attackers to trick operators into granting unauthorized permissions to specific users.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"matrix_irc_bridge","vendor":"matrix"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"matrix-appservice-irc is an open source Node.js IRC bridge for Matrix. The Internet Relay Chat (IRC) protocol allows you to specify multiple modes in a single mode command. Due to a bug in the underlying matrix-org/node-irc library, affected versions of matrix-appservice-irc perform parsing of such modes incorrectly, potentially resulting in the wrong user being given permissions. Mode commands can only be executed by privileged users, so this can only be abused if an operator is tricked into running the command on behalf of an attacker. The vulnerability has been patched in matrix-appservice-irc 0.35.0. As a workaround users should refrain from entering mode commands suggested by untrusted users. Avoid using multiple modes in a single command.","ecosystems":["npm"],"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":"IRC mode parameter confusion in matrix-appservice-irc","id":"CVE-2022-39202","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"privilege_escalation","year":"2022"},"n_packages":2,"n_references":3,"next":{"headline":"Parsing issue in matrix-org/node-irc leading to room takeovers","id":"CVE-2022-39203"},"packages":[{"ecosystem":"npm","fixed":["0.35.0"],"introduced":["0"],"last_affected":[],"package":"matrix-appservice-irc","purl":null,"source":"GHSA-cq7q-5c67-w39w"},{"ecosystem":"npm","fixed":["0.35.0"],"introduced":["0"],"last_affected":[],"package":"matrix-appservice-irc","purl":"pkg:npm/matrix-appservice-irc","source":"GHSA-cq7q-5c67-w39w"}],"prev":{"headline":"Data source and plugin proxy endpoints could leak the authentication cookie to some destination plugins","id":"CVE-2022-39201"},"products":["matrix-appservice-irc"],"published":"2022-09-13","related":[{"cvss_score":8.8,"headline":"Parsing issue in matrix-org/node-irc leading to room takeovers","id":"CVE-2022-39203","kev_date_added":null,"published":"2022-09-13"},{"cvss_score":8,"headline":"Improper handling of multiline messages in matrix-appservice-irc","id":"CVE-2022-29166","kev_date_added":null,"published":"2022-05-05"},{"cvss_score":5.8,"headline":"matrix-appservice-irc IRC command injection via admin commands containing newlines","id":"CVE-2023-38690","kev_date_added":null,"published":"2023-08-04"},{"cvss_score":4.6,"headline":"matrix-appservice-irc PgDataStore.ts sql injection","id":"CVE-2022-3971","kev_date_added":null,"published":"2022-11-13"},{"cvss_score":3.5,"headline":"matrix-appservice-irc events can be crafted to leak parts of targeted messages from other bridged rooms","id":"CVE-2023-38700","kev_date_added":null,"published":"2023-08-04"},{"cvss_score":2.7,"headline":"Matrix IRC Bridge allows IRC command injection to own puppeted user","id":"CVE-2025-27146","kev_date_added":null,"published":"2025-02-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["matrix-org"]},"summary":"Incorrect parsing of IRC mode commands allows attackers to trick operators into granting unauthorized permissions to specific users.","url":"https://insights.sbomify.com/CVE-2022-39202/"}
