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-2026-27613 in the wild and no public exploit code.\n\nAffected product: maximmasiutin TinyWeb. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-27613/ (Markdown: https://insights.sbomify.com/CVE-2026-27613/index.md)","id":"CVE-2026-27613","markdown":"https://insights.sbomify.com/CVE-2026-27613/index.md","name":"CVE-2026-27613","record":{"aliases":["GHSA-rfx5-fh9m-9jj9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"TinyWeb web server","requires_auth":"none","summary":"Unauthenticated attackers can bypass CGI security controls in TinyWeb to achieve remote code execution or source code disclosure.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tinyweb","vendor":"ritlabs"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. A vulnerability in versions prior to 2.01 allows unauthenticated remote attackers to bypass the web server's CGI parameter security controls. Depending on the server configuration and the specific CGI executable in use, the impact is either source code disclosure or remote code execution (RCE). Anyone hosting CGI scripts (particularly interpreted languages like PHP) using vulnerable versions of TinyWeb is impacted. The problem has been patched in version 2.01. If upgrading is not immediately possible, ensure `STRICT_CGI_PARAMS` is enabled (it is defined by default in `define.inc`) and/or do not use CGI executables that natively accept dangerous command-line flags (such as `php-cgi.exe`). If hosting PHP, consider placing the server behind a Web Application Firewall (WAF) that explicitly blocks URL query string parameters that begin with a hyphen (`-`) or contain encoded double quotes (`%22`).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"CGI Parameter Injection (Bypass of STRICT_CGI_PARAMS and EscapeShellParam)","id":"CVE-2026-27613","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Bugsink is vulnerable to Stored XSS via Pygments fallback in stacktrace rendering","id":"CVE-2026-27614"},"packages":[],"prev":{"headline":"Repostat Vulnerable to Reflected Cross-Site Scripting (XSS) via repo prop in RepoCard","id":"CVE-2026-27612"},"products":["TinyWeb"],"published":"2026-02-25","related":[{"cvss_score":10,"headline":"TinyWeb CGI Command Injection","id":"CVE-2026-22781","kev_date_added":null,"published":"2026-01-12"},{"cvss_score":9.3,"headline":"TinyWeb: Integer Overflow in `_Val` (HTTP Request Smuggling)","id":"CVE-2026-28497","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":9.2,"headline":"TinyWeb: HTTP Header Control Character Injection into CGI Environment","id":"CVE-2026-29046","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":8.7,"headline":"TinyWeb vulnerable to Remote Denial of Service via Thread/Connection Exhaustion (Slowloris)","id":"CVE-2026-27630","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":8.7,"headline":"TinyWeb has Unbounded Content-Length Memory Exhaustion (DoS)","id":"CVE-2026-27633","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":8.6,"headline":"Denial of service in n/a","id":"CVE-2024-34199","kev_date_added":null,"published":"2024-05-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["maximmasiutin"]},"summary":"Unauthenticated attackers can bypass CGI security controls in TinyWeb to achieve remote code execution or source code disclosure.","url":"https://insights.sbomify.com/CVE-2026-27613/"}
