Description

This security bulletin contains information about 1 vulnerability.


1) Cross-site scripting (CVE-ID: CVE-2026-49264)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]


The vulnerability allows a remote attacker to execute arbitrary JavaScript in a client application's origin.

The vulnerability exists due to improper neutralization of input during web page generation in the RevocationEndpoint when processing JSONP revocation requests with attacker-controlled callback parameters. A remote attacker can supply a crafted callback parameter to execute arbitrary JavaScript in a client application's origin.

The JSONP feature is disabled by default and exploitation requires a browser page to load the response as JSONP.
