Description

Impact

Pages can gain script or programming rights when they contain a link and the target of the link is renamed or moved. This might lead to execution of scripts contained in xobjects that should have never been executed. This vulnerability affects all version of XWiki since 8.2 and 7.4.5.

Patches

The patch consists in only setting the originalMetadataAuthor when performing such change, so that it's displayed in the history but it has no impact on the right evaluation (i.e. the original author of the changes is still used for right computation).

This patch has been applied on XWiki 16.4.7, 17.1.0RC1, 16.10.4.

Workarounds

There's no workaround for this vulnerability, except preventing to perform any refactoring operation with users having more than edit rights. Administrators are strongly advised to upgrade. If not possible, the patch only impacts module xwiki-platform-refactoring-default so it's possible to apply the commit and rebuild and deploy only that module.

CVSS explanation

Attack vector: Network - Always for XWiki. Complexity: Low - The set of operations to perform the attack is quite easy. Attack requirements: None - Any system is vulnerable, it doesn't depend on specific condition other than user interaction. Privileges required: Low - The attacker only needs edit rights. User interaction: Active - To be successful the attack needs someone with more rights to perform a move/rename of a specific page. Confidentiality: High - The attack might lead to execution of any script. Integrity: High - The attack might lead to execution of any script. Availability: High - The attack might lead to execution of any script. Subsequent system impacts: None for any criteria. Only current system is affected.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-refactoring-default, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.xwiki.platform:xwiki-platform-refactoring-default to 17.1.0-rc-1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-49580 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
