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-2026-91767 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-2026-91767/ (Markdown: https://insights.sbomify.com/CVE-2026-91767/index.md)","id":"CVE-2026-91767","markdown":"https://insights.sbomify.com/CVE-2026-91767/index.md","name":"CVE-2026-91767","record":{"aliases":["AZL-104922","BELL-CVE-2026-91767","BIT-libphp-2026-91767","BIT-php-2026-91767","BIT-php-min-2026-91767","CLEANSTART-2026-JC19240","DEBIAN-CVE-2026-91767","ECHO-3b9e-4caf-d695","MINI-34hm-g6fr-98rp","MINI-4f22-3c7h-qh22","MINI-4qgq-x6pg-5cgp","MINI-765p-gm58-rrrv","MINI-j96g-f62q-x352","MINI-jm6w-q8r7-4qrx","MINI-pwmq-8hj2-9pqj","MINI-q3qx-9c8q-5j75","UBUNTU-CVE-2026-91767"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PHP OpenSSL extension","requires_auth":"none","summary":"A malicious TLS server can trigger a heap buffer overflow in PHP's OpenSSL extension, potentially causing denial of service or arbitrary code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-122","name":"Heap-based Buffer Overflow"}],"description":"php_openssl_matches_wildcard_name() in ext/openssl/xp_ssl.c underflows the length argument passed to memchr() when a TLS server certificate presents a wildcard name whose literal characters are together longer than the hostname being verified.
