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-2026-45062 exists.\n\nAffected packages and fixed versions:\n- github.com/dunglas/frankenphp (Go): affected from 1.11.2; fixed in 1.12.3\n- github.com/dunglas/frankenphp (Go): affected from 1.11.2; fixed in 1.12.3\n- github.com/dunglas/frankenphp (Go): affected from 1.11.2; fixed in 1.12.3\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-2026-45062/ (Markdown: https://insights.sbomify.com/CVE-2026-45062/index.md)","id":"CVE-2026-45062","markdown":"https://insights.sbomify.com/CVE-2026-45062/index.md","name":"CVE-2026-45062","record":{"aliases":["GHSA-3g8v-8r37-cgjm","GO-2026-5084"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP application server","requires_auth":"none","summary":"An attacker can execute arbitrary code by crafting URLs that exploit unsafe Unicode handling in path splitting, allowing non-PHP files to be executed as scripts.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-178","name":"Improper Handling of Case Sensitivity"},{"id":"CWE-176","name":"Improper Handling of Unicode Encoding"}],"description":"FrankenPHP is a modern application server for PHP. From version 1.11.2 to before version 1.12.3, the splitPos() function in cgi.go misuses golang.org/x/text/search with search.IgnoreCase when the request path contains a non-ASCII byte. Two distinct flaws in that fallback let an attacker mislead FrankenPHP into treating a non-.php file as a .php script. In any deployment where the attacker can place content into a file served by FrankenPHP (uploads, file storage, etc.), this can be escalated to remote code execution by crafting a URL whose path triggers either flaw.
