CVE-2026-20149 describes a cross-site scripting (XSS) vulnerability in Cisco Webex, stemming from improper filtering of user-supplied input. An unauthenticated, remote attacker could have exploited this by tricking a user into clicking a malicious link, potentially leading to an XSS attack against the targeted user. Rated as MEDIUM severity with a CVSS score of 6.1, this vulnerability requires user interaction (UI:R) and has low impact on confidentiality and integrity (C:L, I:L). Cisco has already addressed this issue, and there is no evidence of active exploitation, publicly available exploit code, or significant community discussion, with its EPSS score being very low.
