XSS in Apache Answer AI Answer Rendering

IdentifiersCVE-2026-25688CWE-79

CVE-2026-25688 is a cross-site scripting vulnerability in Apache Answer affecting versions through 2.0.0. The issue is described as improper neutralization of alternate XSS syntax: AI-generated response content was rendered in the browser without proper sanitization, allowing attacker-controlled or malicious script content embedded in that rendered output to execute when viewed. Based on the available information, the vulnerable condition is in the rendering path for AI-generated answers or response content displayed to users in the web interface.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary script execution in the context of a victim user's browser session when the victim views affected AI-generated content. This can enable session theft, unauthorized actions performed as the victim, content manipulation, credential or token exfiltration from the application context, and other browser-based follow-on activity typical of stored or rendered XSS.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, reduce exposure by disabling or restricting features that render AI-generated response content, applying strict server-side sanitization to rendered AI output, and enforcing a restrictive Content Security Policy to limit script execution. However, the primary recommended action is to upgrade to 2.0.1, and no complete vendor-provided workaround is available in the supplied content.

Remediation

Patch, then assume compromise.

Upgrade Apache Answer to version 2.0.1 or later. The vendor states that version 2.0.1 fixes the issue by addressing the improper sanitization of AI-generated response content before browser rendering.
