Attackers can exploit this to perform internal port scanning, probe internal-only services and cloud metadata endpoints, and trigger GET-based side effects on internal systems, bypassing network perimeter controls since the request originates from the web server.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N","version":"4.0"},{"score":6.4,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"},{"score":5.3,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":6.4,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794604663633,"publishedAt":1794603799812,"references":[{"source":"CNA: VulnCheck","tags":["release-notes","patch"],"url":"https://wordpress.org/plugins/post-to-google-my-business/#developers"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/post-to-google-my-business-wordpress-plugin-ssrf-via-preview-rest-route"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://wordpress.org/plugins/post-to-google-my-business/#developers"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/post-to-google-my-business-wordpress-plugin-ssrf-via-preview-rest-route"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
