The mcs value reaches mc_search_results() in src/my-calendar-search.php without bracket encoding before do_shortcode runs, so a GET request triggers shortcodes on any page or post, enabling content injection and spoofing.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5},"cwes":["CWE-94"],"references":["https://github.com/joedolson/my-calendar","https://github.com/joedolson/my-calendar/blob/v3.8.10/src/my-calendar-search.php#L170","https://github.com/joedolson/my-calendar/commit/de875c25d9651abb041b2dfe32f60a4320c66496","https://github.com/joedolson/my-calendar/releases/tag/v3.8.11","https://www.vulncheck.com/advisories/my-calendar-3.8.8-before-3.8.11-unauthenticated-shortcode-injection-via-mcs-parameter"],"products":[],"source":"nvd","synced_at":"2026-10-30T16:41:48.501372702+00:00"},"epss":null,"kev":null,"osv":[],"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).
