SQL injection in LimeSurvey Community Edition 7.0.5 exposes the Central Participant Database (CPDB) token-copy workflow to authenticated database exfiltration. An attacker with survey-level access can inject malicious SQL through unsanitized `participantId`, `surveyId`, `tokenFieldname`, and `participantAttributeId` parameters in `Participant.php`, achieving high-confidence read access to the underlying database with limited write impact. No public exploit identified at time of analysis; a vendor fix is available as a GitHub commit but a formally versioned patched release is not independently confirmed.

Reflected XSS in LimeSurvey Community Edition 7.0.5 allows an unauthenticated attacker to execute arbitrary JavaScript in the browser session of an authenticated administrator by delivering a crafted URL targeting the HTML editor popup endpoint. The `text` and `name` query parameters bypass a blacklist-based sanitizer and are rendered unencoded across at least four distinct output contexts - an HTML title element, a JavaScript `window.status` assignment, and multiple `document.getElementById()` calls - confirmed by the patch commit diff. No public exploit has been identified at time of analysis, but an upstream fix is available as a merged GitHub commit and a vendor patch is listed as available.

Server-side request forgery in LimeSurvey through versions 6.17.10 and 7.0.4 exposes internal network infrastructure and cloud instance metadata to authenticated attackers via the REST API survey template endpoint. The vulnerability stems from unsanitized use of the HTTP Host header inside the getTemplateData() function, enabling the application server to be weaponized as a proxy to reach internal services and cloud metadata APIs such as AWS IMDSv1 at 169.254.169.254, potentially yielding IAM role credentials. A public proof-of-concept exploit is available via GitHub, raising the urgency of remediation despite the absence of a CISA KEV listing; no public exploit identified at time of analysis for active in-the-wild campaigns, but POC lowers the bar significantly for opportunistic exploitation.

SQL injection in LimeSurvey's RemoteControl API (invite_participants and remind_participants methods) allows an authenticated attacker with tokens/update permission on a survey to execute arbitrary stacked SQL queries against the application database. Because PDO emulated prepared statements are enabled and MySQL multi-statements are not disabled, attackers can read administrator bcrypt hashes via time-based blind techniques or directly overwrite credentials for instant account takeover. No public exploit identified at time of analysis; the upstream fix is published as LimeSurvey PR #5031, which replaces unsafe string concatenation with parameterized addInCondition().

Account takeover in LimeSurvey is possible through host header injection in the forgotten-password workflow, where reset links are built from the client-supplied HTTP Host header without validation. Remote unauthenticated attackers who know a target's username and email can submit a password-reset request with a spoofed Host header, causing LimeSurvey to email the victim a reset link pointing to an attacker-controlled host while still embedding the valid reset token. Reported by VulnCheck with publicly available exploit code exists via the vendor PR diff, though no public exploit identified at time of analysis in CISA KEV.
