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-2025-49007 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- rack (RubyGems): affected from 3.1.0; fixed in 3.1.16\n- rack (RubyGems): affected from 3.1.0; fixed in 3.1.16\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-2025-49007/ (Markdown: https://insights.sbomify.com/CVE-2025-49007/index.md)","id":"CVE-2025-49007","markdown":"https://insights.sbomify.com/CVE-2025-49007/index.md","name":"CVE-2025-49007","record":{"aliases":["DEBIAN-CVE-2025-49007","GHSA-47m2-26rw-j2jw","MINI-fwgc-fqwr-rc6h"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby web server interface","requires_auth":"none","summary":"Attackers can cause denial of service in Rack-based applications via crafted Content-Disposition headers in multipart requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"rack","vendor":"rack"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U","version":"4.0"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Rack is a modular Ruby web server interface. Starting in version 3.1.0 and prior to version 3.1.16, there is a denial of service vulnerability in the Content-Disposition parsing component of Rack. This is very similar to the previous security issue CVE-2022-44571. Carefully crafted input can cause Content-Disposition header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. This header is used typically used in multipart parsing. Any applications that parse multipart posts using Rack (virtually all Rails applications) are impacted. Version 3.1.16 contains a patch for the vulnerability.","ecosystems":["RubyGems"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"ReDoS Vulnerability in Rack::Multipart handle_mime_head","id":"CVE-2025-49007","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":2,"n_references":3,"next":{"headline":"Atheos Improper Input Validation Vulnerability Enables RCE in Common.php","id":"CVE-2025-49008"},"packages":[{"ecosystem":"RubyGems","fixed":["3.1.16"],"introduced":["3.1.0"],"last_affected":[],"package":"rack","purl":null,"source":"GHSA-47m2-26rw-j2jw"},{"ecosystem":"RubyGems","fixed":["3.1.16"],"introduced":["3.1.0"],"last_affected":[],"package":"rack","purl":"pkg:gem/rack","source":"GHSA-47m2-26rw-j2jw"}],"prev":{"headline":"Wasp has case insensitive OAuth ID vulnerability","id":"CVE-2025-49006"},"products":["rack"],"published":"2025-06-04","related":[{"cvss_score":7.5,"headline":"Rack: Local file inclusion in `Rack::Static` via URL Prefix Matching","id":"CVE-2026-34785","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.5,"headline":"Rack: Algorithmic-Complexity DoS in Rack::Multipart::Parser","id":"CVE-2026-34827","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.5,"headline":"Rack: Denial of Service via Unbounded Multipart File Upload Without Content-Length","id":"CVE-2026-34829","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.5,"headline":"Rack has a Directory Traversal via Rack:Directory","id":"CVE-2026-22860","kev_date_added":null,"published":"2026-02-18"},{"cvss_score":7.5,"headline":"Rack is vulnerable to a memory-exhaustion DoS through unbounded URL-encoded body parsing","id":"CVE-2025-61919","kev_date_added":null,"published":"2025-10-10"},{"cvss_score":7.5,"headline":"Rack's unbounded multipart preamble buffering enables DoS (memory exhaustion)","id":"CVE-2025-61770","kev_date_added":null,"published":"2025-10-07"},{"cvss_score":7.5,"headline":"Rack's multipart parser buffers large non‑file fields entirely in memory, enabling DoS (memory exhaustion)","id":"CVE-2025-61771","kev_date_added":null,"published":"2025-10-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"partial"},"state":"PUBLISHED","updated":"2025-06-05","vendors":["rack"]},"summary":"Attackers can cause denial of service in Rack-based applications via crafted Content-Disposition headers in multipart requests.","url":"https://insights.sbomify.com/CVE-2025-49007/"}
