{"cve":"CVE-2023-36474","nvd":{"published":"2023-06-28T22:15:09.503","modified":"2026-06-17T06:06:20.600","status":"Modified","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/projectdiscovery/interactsh/issues/136","https://github.com/projectdiscovery/interactsh/pull/155","https://github.com/projectdiscovery/interactsh/security/advisories/GHSA-m36x-mgfh-8g78","https://labs.detectify.com/2014/10/21/hostile-subdomain-takeover-using-herokugithubdesk-more/","https://github.com/projectdiscovery/interactsh/issues/136"],"products":["projectdiscovery:interactsh"],"source":"nvd","synced_at":"2026-10-19T21:38:30.124994567+00:00"},"epss":{"cve":"CVE-2023-36474","score":0.00539,"percentile":0.45376,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m36x-mgfh-8g78","url":"https://osv.dev/vulnerability/GHSA-m36x-mgfh-8g78","summary":"Subdomain Takeover in Interactsh server","modified":"2026-09-10T03:49:10.822901400Z","packages":[{"ecosystem":"Go","name":"github.com/projectdiscovery/interactsh","purl":"pkg:golang/github.com/projectdiscovery/interactsh","ranges":["<1.0.0"],"fixed":["1.0.0"]}]},{"id":"GO-2022-0372","url":"https://osv.dev/vulnerability/GO-2022-0372","summary":"Subdomain Takeover in Interactsh server in github.com/projectdiscovery/interactsh","modified":"2026-03-03T04:52:09.223807Z","packages":[{"ecosystem":"Go","name":"github.com/projectdiscovery/interactsh","purl":"pkg:golang/github.com/projectdiscovery/interactsh","ranges":["<1.0.0"],"fixed":["1.0.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
