{"id":"CVE-2026-53510","aliases":["GHSA-mx5j-mp4f-g8jg"],"url":"https://o3.security/vulnerability/CVE-2026-53510","summary":"Savon::Model evaluates WSDL operation names as Ruby source","details":"### Impact\n\n`Savon::Model` generated SOAP operation methods by interpolating operation names into Ruby source passed to `module_eval`. An attacker who can control the operation names of a WSDL, can inject Ruby code that executes in the application process. This affects only the `.all_operations` class method provided by `Savon::Model` to automatically register all operations provided by the WSDL. Configuring `Savon::Model` with trusted operation names via `.operations` is safe.\n\n### Patches\n\nPatched in Savon 2.17.2.\n\nUsers should upgrade to 2.17.2 or later.\n\n### Workarounds\n\nAvoid `.all_operations` for untrusted WSDL documents. Use `.operations` with trusted operation names instead.","published":"2026-07-31T19:38:33.457Z","modified":"2026-10-28T02:30:48.294939984Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00418,"percentile":0.35647,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"savon","fixedVersion":"2.17.2"}],"fix":{"url":"https://github.com/savonrb/savon/commit/8f22eb543e7436f6247172c9be47e22792d375e9","label":"savonrb/savon@8f22eb5"},"references":[{"type":"WEB","url":"https://github.com/savonrb/savon/releases/tag/v2.17.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53510.json"},{"type":"ADVISORY","url":"https://github.com/savonrb/savon/security/advisories/GHSA-mx5j-mp4f-g8jg"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53510"},{"type":"FIX","url":"https://github.com/savonrb/savon/commit/8f22eb543e7436f6247172c9be47e22792d375e9"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/savon/CVE-2026-53510.yml"},{"type":"PACKAGE","url":"https://github.com/savonrb/savon"},{"type":"WEB","url":"https://www.cve.org/CVERecord/SearchResults?query=CVE-2026-53510"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:48.294939984Z"}}
