Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88916 in the wild and no public exploit code.\n\nAffected product: TÜBİTAK ULAKBİM UlakPDF. 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-2026-88916/ (Markdown: https://insights.sbomify.com/CVE-2026-88916/index.md)","id":"CVE-2026-88916","markdown":"https://insights.sbomify.com/CVE-2026-88916/index.md","name":"CVE-2026-88916","record":{"aliases":["GHSA-6gp4-g9px-6pmh"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"UlakPDF application","requires_auth":"low_privilege","summary":"Attackers can bypass admin authentication via header fallback to gain privileged access in UlakPDF.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TR-CERT","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Incorrect Authorization vulnerability in TÜBİTAK ULAKBİM UlakPDF allows Privilege Escalation.\n\nThis issue affects UlakPDF: through 09092026.","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":"Admin Access Bypass via Header Fallback in TÜBİTAK ULAKBİM's UlakPDF","id":"CVE-2026-88916","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache WSS4J: SAML Sender-Vouches Authentication Bypass","id":"CVE-2026-88920"},"packages":[],"prev":{"headline":"MISP Event Template Instantiation Bypasses Sharing Group and Tagging Authorization","id":"CVE-2026-88915"},"products":["UlakPDF"],"published":"2026-09-24","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":"total"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["TÜBİTAK ULAKBİM"]},"summary":"Attackers can bypass admin authentication via header fallback to gain privileged access in UlakPDF.","url":"https://insights.sbomify.com/CVE-2026-88916/"}
