A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade redcap/redcap to 14.2.1.

AI-suggested

To mitigate this vulnerability, European organizations using REDCap should urgently upgrade to version 14.2.1 or later, where the issue is fixed. Beyond patching, administrators should implement strict input validation and output encoding on all user-supplied content fields, especially those rendered in public-facing components. Employing Content Security Policy (CSP) headers can help limit the impact of any injected scripts by restricting the sources from which scripts can be loaded. Regular security audits and penetration testing focused on web application vulnerabilities should be conducted to detect similar issues proactively. Additionally, organizations should review user access controls to limit authenticated user permissions, reducing the risk of malicious payload injection. Educating users about phishing and social engineering risks related to malicious survey links can also reduce exploitation likelihood. Finally, monitoring web logs for unusual activity on survey endpoints can provide early detection of exploitation attempts.

Description

A stored cross-site scripting (XSS) vulnerability in the Public Survey function of REDCap 13.1.9 allows authenticated users to execute arbitrary web script or HTML by injecting a crafted payload into the 'Survey Title' and 'Survey Instructions' fields. This vulnerability could be exploited by attackers to execute malicious scripts when the survey is accessed through its public link. It is advised to update to version 14.2.1 or later to fix this issue.

Impact

For European organizations, especially those in healthcare, academic research, and clinical trial sectors where REDCap is commonly used, this vulnerability poses a substantial risk. Exploitation could lead to unauthorized access to sensitive personal and medical data, undermining confidentiality and potentially violating GDPR requirements. Attackers could leverage the XSS flaw to steal session cookies, impersonate legitimate users, or distribute malicious payloads to survey respondents, damaging organizational reputation and trust. Given that REDCap surveys are often distributed widely via public links, the attack surface is broad, increasing the likelihood of victim exposure. Additionally, compromised surveys could be used to manipulate data integrity or disrupt availability by injecting scripts that alter survey behavior or cause denial of service. The impact extends beyond individual organizations to potentially affect collaborative research projects and multi-institutional studies common in Europe.
