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-2025-27149 in the wild and no public exploit code.\n\nAffected product: zulip. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2025-27149/ (Markdown: https://insights.sbomify.com/CVE-2025-27149/index.md)","id":"CVE-2025-27149","markdown":"https://insights.sbomify.com/CVE-2025-27149/index.md","name":"CVE-2025-27149","record":{"aliases":["GHSA-358p-x39m-99mm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Zulip team chat","requires_auth":"high_privilege","summary":"Zulip server exports leak private user-agent data and private channel metadata to administrators, exposing sensitive information without consent.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"zulip_server","vendor":"zulip"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-497","name":"Exposure of Sensitive System Information to an Unauthorized Control Sphere"}],"description":"Zulip server provides an open-source team chat that helps teams stay productive and focused.

The collection of user-agent types identifying specific integrations or HTTP libraries (E.g., ZulipGitlabWebhook, okhttp, or PycURL) that have been used to access any organization on the server was incorrectly included in all three export types, regardless of if they were used to access the exported organization or not.
