By setting social_site=true and manipulating the user_id_social_site parameter, an attacker can generate a valid WordPress session cookie for any user ID, including administrators. Once authenticated, the attacker may exploit plugin upload functionality to install a malicious plugin containing arbitrary PHP code, resulting in remote code execution on the underlying server.","published":"2025-07-09T01:15:50.000Z","lastModified":"2026-06-17T09:13:26.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":10,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-94","CWE-306","CWE-434"],"affected":[],"epss":{"score":0.16514,"percentile":0.96997,"date":"2026-11-01","history":[{"date":"2026-09-29","score":0.16203,"percentile":0.96838}]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2025-07-22","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52370,"kind":"exploit","title":"Pie Register WordPress Plugin 3.7.1.4 - Authentication Bypass to RCE","url":"https://www.exploit-db.com/exploits/52370","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/webapps/52370.py","file":"exploits/multiple/webapps/52370.py","published":"2025-07-22","added":"2025-07-22","updated":"2025-07-22","author":"Md Amanat Ullah (xSwads)","type":"webapps","platform":"multiple","port":null,"verified":false,"codes":["CVE-2025-34077"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 16.5%, higher than 97% of all known CVEs.
