Clients with write access to an object in a class with a trigger or LiveQuery can corrupt a built-in function, making unrelated requests fail until restart and denying service to all clients and hosted applications.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":5.3,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},{"score":6,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/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":5.3,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793809070050,"publishedAt":1793806407391,"references":[{"source":"CNA: VulnCheck","tags":["vendor-advisory"],"url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-95hp-82c6-25q5"},{"source":"CNA: VulnCheck","tags":["patch","issue-tracking"],"url":"https://github.com/parse-community/parse-server/pull/10810"},{"source":"CNA: VulnCheck","tags":["patch","issue-tracking"],"url":"https://github.com/parse-community/parse-server/pull/10811"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/parse-server-before-8.6.113-and-9.10.6-alpha.5-prototype-pollution-via-dot-notation-key"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/parse-community/parse-server/pull/10810"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/parse-community/parse-server/pull/10811"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-95hp-82c6-25q5"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/parse-server-before-8.6.113-and-9.10.6-alpha.5-prototype-pollution-via-dot-notation-key"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
