CVE-2023-26446 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. The users clientID at "application passwords" was not sanitized or escaped before being added to DOM. Malicious script code can be executed within the victims context. EPSS estimates a 0.56% chance of exploitation in the next 30 days.

Description

The users clientID at "application passwords" was not sanitized or escaped before being added to DOM. Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface and API. To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. We now sanitize the user-controllable clientID parameter. No publicly available exploits are known.
