{"id":"CVE-2023-36474","aliases":["GHSA-m36x-mgfh-8g78","GO-2022-0372"],"url":"https://o3.security/vulnerability/CVE-2023-36474","summary":"Interactsh server settings make users vulnerable to Subdomain Takeover","details":"Interactsh is an open-source tool for detecting out-of-band interactions. Domains configured with interactsh server prior to version 1.0.0 were vulnerable to subdomain takeover for a specific subdomain, i.e `app.` Interactsh server used to create cname entries for `app` pointing to `projectdiscovery.github.io` as default, which intended to used for hosting interactsh web client using GitHub pages. This is a security issue with a self-hosted interactsh server in which the user may not have configured a web client but still have a CNAME entry pointing to GitHub pages, making them vulnerable to subdomain takeover. This allows a threat actor to host / run arbitrary client side code (cross-site scripting) in a user's browser when browsing the vulnerable subdomain. Version 1.0.0 fixes this issue by making CNAME optional, rather than default.","published":"2023-06-28T21:20:22.455Z","modified":"2026-08-12T03:51:14.702593779Z","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/projectdiscovery/interactsh","fixedVersion":"1.0.0"}],"fix":{"url":"https://github.com/projectdiscovery/interactsh/pull/155","label":"projectdiscovery/interactsh#155"},"references":[{"type":"WEB","url":"https://labs.detectify.com/2014/10/21/hostile-subdomain-takeover-using-herokugithubdesk-more/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/36xxx/CVE-2023-36474.json"},{"type":"ADVISORY","url":"https://github.com/projectdiscovery/interactsh/security/advisories/GHSA-m36x-mgfh-8g78"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-36474"},{"type":"REPORT","url":"https://github.com/projectdiscovery/interactsh/issues/136"},{"type":"FIX","url":"https://github.com/projectdiscovery/interactsh/pull/155"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:14.702593779Z"}}
