Attackers have exploited CVE-2026-109618 in the wild since at least 26 Oct 2026.\n\nAffected packages and fixed versions:\n- libphp (Bitnami): affected from 7.3.0; fixed in 8.2.35, 8.3.36, 8.4.27, 8.5.12\n- php (Bitnami): affected from 7.3.0; fixed in 8.2.35, 8.3.36, 8.4.27, 8.5.12\n- php-min (Bitnami): affected from 7.3.0; fixed in 8.2.35, 8.3.36, 8.4.27, 8.5.12\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-2026-109618/ (Markdown: https://insights.sbomify.com/CVE-2026-109618/index.md)","id":"CVE-2026-109618","markdown":"https://insights.sbomify.com/CVE-2026-109618/index.md","name":"CVE-2026-109618","record":{"aliases":["AZL-109815","BELL-CVE-2026-109618","BIT-libphp-2026-109618","BIT-php-2026-109618","BIT-php-min-2026-109618","CLEANSTART-2026-LE11033","DEBIAN-CVE-2026-109618","ECHO-3b6e-9e7f-34fe","ROOT-OS-ALPINE-315-CVE-2026-109618","ROOT-OS-ALPINE-318-CVE-2026-109618","ROOT-OS-UBUNTU-2004-CVE-2026-109618","ROOT-OS-UBUNTU-2504-CVE-2026-109618","ROOT-OS-UBUNTU-2510-CVE-2026-109618","UBUNTU-CVE-2026-109618","openSUSE-SU-2026:12228-1"],"analysis":null,"analysis_generated_by":null,"assigner":"php","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"},{"product":"panorama_virtual_appliance","vendor":"paloaltonetworks"},{"product":"php","vendor":"php"},{"product":"ruggedcom_ape1808_firmware","vendor":"siemens"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-824","name":"Access of Uninitialized Pointer"},{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-1419","name":"Incorrect Initialization of Resource"},{"id":"CWE-1325","name":"Improperly Controlled Sequential Memory Allocation"}],"description":"PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context and abort handling of the request.
