It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-25704 in the wild and no public exploit code.\n\nAffected product: pop-os cosmic-greeter. 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-2026-25704/ (Markdown: https://insights.sbomify.com/CVE-2026-25704/index.md)","id":"CVE-2026-25704","markdown":"https://insights.sbomify.com/CVE-2026-25704/index.md","name":"CVE-2026-25704","record":{"aliases":["GHSA-h5vx-6jh5-qhq7"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cosmic Greeter","requires_auth":"low_privilege","summary":"An attacker can exploit a race condition in cosmic-greeter to regain dropped privileges and escalate their access rights.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"},{"id":"CWE-271","name":"Privilege Dropping / Lowering Errors"}],"description":"A Privilege Dropping / Lowering Errors/Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in  cosmic-greeter can allow an attacker to regain privileges that should have been dropped and abuse them in the racy checking logic.\n\nThis issue affects cosmic-greeter before https://github.Com/pop-os/cosmic-greeter/pull/426.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Incomplete privilege drop for com.system76.CosmicGreeter.GetUserData","id":"CVE-2026-25704","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Rancher Extensions have arbitrary file access via path traversal","id":"CVE-2026-25705"},"packages":[],"prev":{"headline":"Potential information leakage from manager /network/graph API in NeuVector","id":"CVE-2026-25703"},"products":["cosmic-greeter"],"published":"2026-03-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-04-16","vendors":["pop-os"]},"summary":"An attacker can exploit a race condition in cosmic-greeter to regain dropped privileges and escalate their access rights.","url":"https://insights.sbomify.com/CVE-2026-25704/"}
