CyberRota Analysis

AI-Generated

Koha versions prior to 26.05.02, 25.11.07, and 25.05.13 are vulnerable to a stored cross-site scripting (XSS) flaw in the purchase suggestion handler, allowing authenticated staff users to inject malicious scripts via unsanitized input. This vulnerability can lead to the execution of injected scripts in the browsers of staff users viewing the suggestion list, potentially compromising user sessions or exposing sensitive information. Organizations using affected Koha versions, particularly those with multiple staff users, should prioritize patching to mitigate this risk.

Original NVD Description

Koha before 26.05.02, 25.11.07, and 25.05.13 contains a stored cross-site scripting vulnerability in the purchase suggestion handler that allows authenticated staff users to inject malicious scripts by submitting unsanitized input through the suggestion save operation. Attackers can supply crafted HTML or script content in fields such as title, author, isbn, publishercode, place, collectiontitle, itemtype, and note, which are stored without sanitization and later rendered in the suggestion list template, causing injected scripts to execute in the browser of any staff user who views the suggestions.
