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-2026-79617 in the wild and no public exploit code.\n\nAffected product: TÜBİTAK BİLGEM Software Technologies Research Institute Pardus LightDM 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-2026-79617/ (Markdown: https://insights.sbomify.com/CVE-2026-79617/index.md)","id":"CVE-2026-79617","markdown":"https://insights.sbomify.com/CVE-2026-79617/index.md","name":"CVE-2026-79617","record":{"aliases":["GHSA-3584-rwvv-wp47"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Pardus LightDM Greeter","requires_auth":"low_privilege","summary":"An attacker can exploit incorrect permission assignments in the Pardus LightDM Greeter to expose sensitive display information.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TR-CERT","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Incorrect Permission Assignment for Critical Resource vulnerability in TÜBİTAK BİLGEM Software Technologies Research Institute Pardus LightDM Greeter allows Exploiting Incorrectly Configured Access Control Security Levels.\n\nThis issue affects Pardus LightDM Greeter: before 0.4.15.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-09","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-09T13:39:00Z","kind":"github_poc","ref":"https://github.com/alpernae/CVE-2026-79617","stars":1,"title":"Proof-of-concept demonstrating cross-user X11 session compromise in Pardus LightDM Greeter caused by the unsafe `xhost +local:` configuration, including unauthorized shell access, display access, screen capture, window enumeration, and XTEST input injection."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Improper Access Control Leading to Display Exposure in TÜBİTAK BİLGEM's Pardus LightDM Greeter","id":"CVE-2026-79617","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"WP User Frontend \u003c 4.3.12 - Subscriber+ Post Creation via Subscription-Gated Form","id":"CVE-2026-79618"},"packages":[],"prev":{"headline":"Out-of-bounds read vulnerability in Context2D.path and PathSvg.path properties impacts Qt Quick","id":"CVE-2026-79616"},"products":["Pardus LightDM Greeter"],"published":"2026-09-09","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-09","vendors":["TÜBİTAK BİLGEM Software Technologies Research Institute"]},"summary":"An attacker can exploit incorrect permission assignments in the Pardus LightDM Greeter to expose sensitive display information.","url":"https://insights.sbomify.com/CVE-2026-79617/"}
