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-2004-0189 exists.\n\nAffected product: n/a. 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-2004-0189/ (Markdown: https://insights.sbomify.com/CVE-2004-0189/index.md)","id":"CVE-2004-0189","markdown":"https://insights.sbomify.com/CVE-2004-0189/index.md","name":"CVE-2004-0189","record":{"aliases":["DEBIAN-CVE-2004-0189","DSA-474","GHSA-wgp5-p97p-cph9","RHSA-2004:133"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Squid proxy server","requires_auth":"none","summary":"Remote attackers can bypass URL access control lists in Squid proxy servers by using NULL characters in URLs, allowing unauthorized access to restricted resources.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"squid","vendor":"squid"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[],"description":"The \"%xx\" URL decoding function in Squid 2.5STABLE4 and earlier allows remote attackers to bypass url_regex ACLs via a URL with a NULL (\"%00\") character, which causes Squid to use only a portion of the requested URL when comparing it against the access control lists.","ecosystems":["Red Hat:enterprise_linux:3::as","Red Hat:enterprise_linux:3::desktop","Red Hat:enterprise_linux:3::es","Red Hat:enterprise_linux:3::ws"],"exploits":{"exploitdb":1,"first_seen":"2004-03-01","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2004-03-01","kind":"exploitdb","ref":"23777","stars":null,"title":"Squid Proxy 2.4/2.5 -
