Stored Cross-Site Scripting (XSS) Vulnerability in Teedy v1.5 - v1.9

CVE-2022-22115 · CRITICAL Severity

CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H

In Teedy, versions v1.5 through v1.9 are vulnerable to Stored Cross-Site Scripting (XSS) in the name of a created Tag. Since the Tag name is not being sanitized properly in the edit tag page, a low privileged attacker can store malicious scripts in the name of the Tag. In the worst case, the victim who inadvertently triggers the attack is a highly privileged administrator. The injected scripts can extract the Session ID, which can lead to full Account Takeover of the administrator, and privileges escalation.
