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-2026-91768 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- libphp (Bitnami): affected from 8.2.0; fixed in 8.2.34, 8.3.35, 8.4.26, 8.5.11\n- php (Bitnami): affected from 8.2.0; fixed in 8.2.34, 8.3.35, 8.4.26, 8.5.11\n- php-min (Bitnami): affected from 8.2.0; fixed in 8.2.34, 8.3.35, 8.4.26, 8.5.11\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-2026-91768/ (Markdown: https://insights.sbomify.com/CVE-2026-91768/index.md)","id":"CVE-2026-91768","markdown":"https://insights.sbomify.com/CVE-2026-91768/index.md","name":"CVE-2026-91768","record":{"aliases":["AZL-104895","BELL-CVE-2026-91768","BIT-libphp-2026-91768","BIT-php-2026-91768","BIT-php-min-2026-91768","CLEANSTART-2026-XM64150","DEBIAN-CVE-2026-91768","ECHO-a027-5d9a-9741","MINI-3rrh-7j3v-gw3f","MINI-4hmg-w75g-7p3j","MINI-9rjj-gw8p-rgfr","MINI-h852-rj78-9667","MINI-mchf-p5j9-8jwj","MINI-qhpp-32m2-634c","MINI-wh53-5qj2-545x","MINI-wvh8-cgg4-rp39","UBUNTU-CVE-2026-91768"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"PHP FastCGI","requires_auth":"none","summary":"Attackers can bypass FastCGI client access controls by exploiting a partial IPv6 address comparison, allowing unauthorized access to endpoints.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"php","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-1023","name":"Incomplete Comparison with Missing Factors"}],"description":"The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowed_clients matches on a /96 prefix instead of the exact address.
