The application does not implement any CSRF-protection mechanisms such as tokens, nonces, or same-site cookie restrictions. An attacker can create a malicious HTML page that, when visited by an authenticated user, will automatically submit a forged POST request to the vulnerable endpoint. This request will be executed with the victim's privileges, allowing the attacker to perform unauthorized actions on their behalf, such as sending arbitrary messages in any chat room.","cvss_v4":null,"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-352"],"references":["https://github.com/floccocam-cpu/CVE-Research-2025/blob/main/CVE-2025-63710/README2.md","https://www.sourcecodester.com/php/12295/simple-public-chat-room-using-php.html"],"products":["pijey:simple_public_chat_room"],"source":"nvd","synced_at":"2026-10-19T22:14:53.307938015+00:00"},"epss":{"cve":"CVE-2025-63710","score":0.00158,"percentile":0.04918,"date":"2026-11-01"},"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).
