EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 75% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A Cross-Site Scripting (XSS) vulnerability in Google Cloud Looker versions prior to 25.6.103, 25.12.65, 25.18.68, 26.0.66, 26.2.47, 26.4.36, 26.6.28, and 26.8.7 on Looker-hosted and Self-hosted allows an attacker to execute arbitrary JavaScript leading to administrative account takeover using a maliciously crafted URL.

Looker-hosted and Self-hosted were found to be vulnerable. This issue has already been mitigated for Looker-hosted instances. No user action is required for these.

Self-hosted instances must be upgraded to the patched versions: 25.6.103+, 25.12.65+, 25.18.68+, 26.0.66+, 26.2.47+, 26.4.36+, 26.6.28+, or 26.8.7+.
