An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-45286 exists.\n\nAffected packages and fixed versions:\n- github.com/mccutchen/go-httpbin (Go): affected all versions; no fix listed\n- github.com/mccutchen/go-httpbin (Go): affected all versions; fixed in 2.18.0\n- github.com/mccutchen/go-httpbin (Go): affected all versions; fixed in 2.18.0\n- github.com/mccutchen/go-httpbin/v2 (Go): affected all versions; fixed in 2.18.0\n- github.com/mccutchen/go-httpbin/v2 (Go): affected all versions; fixed in 2.18.0\n- github.com/mccutchen/go-httpbin/v2 (Go): affected all versions; fixed in 2.18.0\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-2025-45286/ (Markdown: https://insights.sbomify.com/CVE-2025-45286/index.md)","id":"CVE-2025-45286","markdown":"https://insights.sbomify.com/CVE-2025-45286/index.md","name":"CVE-2025-45286","record":{"aliases":["GHSA-528q-4pgm-wvg2","GO-2025-3554"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Go HTTP testing tool","requires_auth":"none","summary":"Attackers can execute arbitrary web scripts or HTML in httpbin via a crafted payload, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"go-httpbin","vendor":"httpbingo"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"A cross-site scripting (XSS) vulnerability in mccutchen httpbin v2.17.1 allows attackers to execute arbitrary web scripts or HTML via a crafted payload.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Reflected XSS in go-httpbin due to unrestricted client control over Content-Type","id":"CVE-2025-45286","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"xss","year":"2025"},"n_packages":6,"n_references":2,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2025-45311"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/mccutchen/go-httpbin","purl":"pkg:golang/github.com/mccutchen/go-httpbin","source":"GO-2025-3554"},{"ecosystem":"Go","fixed":["2.18.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mccutchen/go-httpbin","purl":null,"source":"GHSA-528q-4pgm-wvg2"},{"ecosystem":"Go","fixed":["2.18.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mccutchen/go-httpbin","purl":"pkg:golang/github.com/mccutchen/go-httpbin","source":"GHSA-528q-4pgm-wvg2"},{"ecosystem":"Go","fixed":["2.18.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mccutchen/go-httpbin/v2","purl":null,"source":"GHSA-528q-4pgm-wvg2"},{"ecosystem":"Go","fixed":["2.18.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mccutchen/go-httpbin/v2","purl":"pkg:golang/github.com/mccutchen/go-httpbin/v2","source":"GHSA-528q-4pgm-wvg2"},{"ecosystem":"Go","fixed":["2.18.0"],"introduced":["0"],"last_affected":[],"package":"github.com/mccutchen/go-httpbin/v2","purl":"pkg:golang/github.com/mccutchen/go-httpbin/v2","source":"GO-2025-3554"}],"prev":{"headline":"Server-side request forgery in n/a","id":"CVE-2025-45250"},"products":["n/a"],"published":"2026-01-02","related":[],"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-06","vendors":["n/a"]},"summary":"Attackers can execute arbitrary web scripts or HTML in httpbin via a crafted payload, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2025-45286/"}
