CVE-2025-62527 is a vulnerability classified under CWE-15 (External Control of System or Configuration Setting) affecting Taguette, an open-source qualitative research tool. In versions prior to 1.5.0, an attacker can exploit the password reset functionality by requesting a reset email containing a malicious link. If the victim clicks this link, the attacker gains the ability to set or alter the victim's email address within the system. This manipulation can lead to unauthorized account access or hijacking, as the attacker can redirect password reset processes or notifications to an email they control. The vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R) to click the malicious link. The impact on confidentiality is high since attackers can potentially access sensitive qualitative research data. Integrity impact is low, and availability is not affected. The vulnerability has a CVSS v3.1 score of 7.1, indicating high severity. The issue was publicly disclosed on October 20, 2025, and patched in Taguette version 1.5.0. No known exploits have been reported in the wild to date. The vulnerability highlights the risk of insufficient validation and control over system configuration settings via user-controllable inputs in password reset workflows.

For European organizations, especially universities, research institutions, and companies relying on qualitative data analysis, this vulnerability poses a significant risk. Attackers exploiting this flaw could hijack user accounts by changing email addresses, leading to unauthorized access to sensitive research data, intellectual property, or personal information. This could result in data breaches, loss of confidentiality, and potential reputational damage. Since Taguette is used in academic and social research contexts, compromised data integrity or confidentiality could undermine research validity and privacy compliance, including GDPR obligations. The requirement for user interaction means phishing campaigns could be tailored to exploit this vulnerability, increasing the risk of successful attacks. The lack of known exploits in the wild suggests a window of opportunity for defenders to patch and educate users before widespread exploitation occurs.

1. Immediately upgrade all Taguette installations to version 1.5.0 or later, where the vulnerability is patched. 2. Implement strict validation and sanitization of password reset links and associated parameters to prevent manipulation. 3. Employ multi-factor authentication (MFA) to reduce the impact of compromised credentials or email changes. 4. Educate users about phishing risks, emphasizing caution when clicking password reset or email links. 5. Monitor password reset request logs for unusual activity patterns indicative of exploitation attempts. 6. Restrict password reset functionality to verified email addresses or require additional verification steps before allowing email changes. 7. Conduct regular security audits of open-source tools integrated into organizational workflows to identify and remediate vulnerabilities promptly.
