CVE-2025-49590: XWiki Cryptpad

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

CryptPad is a collaboration suite. Prior to version 2025.3.0, the "Link Bouncer" functionality attempts to filter javascript URIs to prevent Cross-Site Scripting (XSS), however this can be bypassed. There is an "early allow" code path that happens before the URI's protocol/scheme is checked, which a maliciously crafted URI can follow. This issue has been patched in version 2025.3.0.

Affected products

• XWiki Cryptpad: before 2025.3.0 (fixed in 2025.3.0)
