An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-6491 exists.\n\nAffected packages and fixed versions:\n- libphp (Bitnami): affected all versions; fixed in 8.1.33, 8.2.29, 8.3.23, 8.4.10\n- php (Bitnami): affected all versions; fixed in 8.1.33, 8.2.29, 8.3.23, 8.4.10\n- php-min (Bitnami): affected all versions; fixed in 8.1.33, 8.2.29, 8.3.23, 8.4.10\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-2025-6491/ (Markdown: https://insights.sbomify.com/CVE-2025-6491/index.md)","id":"CVE-2025-6491","markdown":"https://insights.sbomify.com/CVE-2025-6491/index.md","name":"CVE-2025-6491","record":{"aliases":["AZL-65118","AZL-65127","BELL-CVE-2025-6491","BIT-libphp-2025-6491","BIT-php-2025-6491","BIT-php-min-2025-6491","CLSA-2025-1754342894","CLSA-2025-1754381195","CLSA-2025-1754384758","CLSA-2025-1760017411","CLSA-2025-1760017744","DEBIAN-CVE-2025-6491","ECHO-950f-f0b4-71aa","GHSA-453j-q27h-5p8x","MINI-j54g-3mg6-pcqw","MINI-pm3g-hpw8-94wp","MINI-qmxg-gxxc-qgj5","MINI-vm4h-96mx-gjx6","UBUNTU-CVE-2025-6491"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP SOAP extension","requires_auth":"none","summary":"Attackers can cause server crashes by sending large XML namespace prefixes to the PHP SOAP extension, impacting availability.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"php","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In PHP versions:8.1.* before 8.1.33, 8.2.* before 8.2.29, 8.3.* before 8.3.23, 8.4.* before 8.4.10 when parsing XML data in SOAP extensions, overly large (\u003e2Gb) XML namespace prefix may lead to null pointer dereference.
