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-2026-17545 exists.\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-2026-17545/ (Markdown: https://insights.sbomify.com/CVE-2026-17545/index.md)","id":"CVE-2026-17545","markdown":"https://insights.sbomify.com/CVE-2026-17545/index.md","name":"CVE-2026-17545","record":{"aliases":["AZL-105141","BIT-libphp-2026-17545","BIT-php-2026-17545","BIT-php-min-2026-17545","MINI-39w4-8p37-7fg8","MINI-3wvm-rghf-5xfc","MINI-5j4g-7p9c-fqhr","MINI-6x8c-pfq4-h3jf","MINI-86pc-ffpf-j58x","MINI-g9rp-mm7x-hqgc","MINI-qrrj-pxxc-m5xp","MINI-vjmw-j8g4-37fq","UBUNTU-CVE-2026-17545"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP interpreter","requires_auth":"none","summary":"Attackers can cause denial of service in PHP on Windows by using reserved device names in file paths, blocking worker processes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"php","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-67","name":"Improper Handling of Windows Device Names"}],"description":"On Windows, PHP's filesystem and stream APIs do not reject reserved device names such as CON, PRN, AUX, NUL, COM1 to COM9, LPT1 to LPT9, CONIN$ and CONOUT$ when they appear as a component of a path.
