CVE-2026-48048: XWiki Platform password hash disclosure in Livetable results

CVE-2026-48048 · Severity: high · CVSS 7.5 · Published 2026-08-10

XWiki is a popular open-source collaborative platform. A security flaw in its 'Livetable' component, which displays data in a searchable table format, allows unauthorized users to extract sensitive information. Specifically, an attacker can reconstruct a user's password hash and salt by sending a series of automated requests, potentially leading to full account takeover.

Technologies: org.xwiki.platform:xwiki-platform-livetable-ui (Maven). Vendors: Maven, Xwiki.

  • org.xwiki.platform:xwiki-platform-livetable-ui (Maven): upgrade to 16.10.17 or later

Technical details

The vulnerability is an information disclosure flaw (CWE-359) in the LiveTableResults component of XWiki Platform. It stems from an insufficient fix for a previous vulnerability where the check for sensitive properties (like passwords and emails) did not account for class names passed via '_class' parameters. By manipulating these parameters, an unauthenticated attacker can perform a side-channel attack to leak password hashes and salts bit-by-bit. An attacker can fully reconstruct a user's credentials in approximately 768 requests. The fix involves adjusting the property class and type checks in the LiveTableResultsMacros.
