EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 83% 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).

LimeSurvey Community Edition 7.0.5 contains a stored cross-site scripting vulnerability in the Survey Menu Entries administration page. An authenticated user with the global settings:read permission can create a survey menu entry containing attacker-controlled data. The value is stored in the surveymenu_entries.data field and later inserted into a single-quoted HTML title attribute without context-appropriate encoding.

This issue affects LimeSurvey: 7.0.5.
