An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-17544 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- libphp (Bitnami): affected from 8.4.0; fixed in 8.4.24, 8.5.9\n- php (Bitnami): affected from 8.4.0; fixed in 8.4.24, 8.5.9\n- php-min (Bitnami): affected from 8.4.0; fixed in 8.4.24, 8.5.9\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-2026-17544/ (Markdown: https://insights.sbomify.com/CVE-2026-17544/index.md)","id":"CVE-2026-17544","markdown":"https://insights.sbomify.com/CVE-2026-17544/index.md","name":"CVE-2026-17544","record":{"aliases":["BIT-libphp-2026-17544","BIT-php-2026-17544","BIT-php-min-2026-17544","DEBIAN-CVE-2026-17544","MINI-24gv-vmvh-87wj","MINI-59fc-23q6-mvr8","UBUNTU-CVE-2026-17544"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP scripting language","requires_auth":"none","summary":"Attackers can trigger out-of-bounds writes in PHP's bccomp function via crafted inputs, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"php","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/AU:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Attacker-provided inputs to bccomp() could lead to an out-of-bounds write with stack and heap corruption in PHP versions from 8.4.* before 8.4.24 and from 8.5.* before 8.5.9.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":"2026-08-12","github_poc":2,"max_poc_stars":6,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-12T17:17:50Z","kind":"github_poc","ref":"https://github.com/Boreas37/CVE-2026-17544-PoC","stars":6,"title":"CVE-2026-17544 — PHP bcmath bccomp() OOB write (stack smashing).
