AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in Docmost, an open-source collaborative wiki and documentation software. Versions before 0.25.0 have a flaw in the public share page functionality where page titles are not properly HTML-escaped before being inserted into meta tags and the title tag.
Because of this improper escaping, an attacker can inject malicious JavaScript code that will be stored and executed whenever any user opens a shared page link. This type of attack is known as Stored Cross-Site Scripting (XSS).
The vulnerability was fixed in version 0.25.0 of Docmost.
How can this vulnerability impact me? :
This vulnerability allows attackers to execute arbitrary JavaScript code in the context of users who open a shared page link in Docmost.
Such execution can lead to theft of sensitive information, session hijacking, or performing actions on behalf of the user without their consent.
The CVSS score of 7.3 indicates a high severity impact on confidentiality and integrity, though availability is not affected.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
