CVE-2026-25810 identifies a missing authorization vulnerability categorized under CWE-862 in the PlaciPy placement management system version 1.0.0 developed by Praskla-Technology. The vulnerability exists specifically in the backend route handling student submissions (backend/src/routes/student.submission.routes.ts), where authentication is enforced but object-level authorization is not. This means that while users must be authenticated to access the endpoint, the system fails to verify whether the authenticated user actually owns or is permitted to access the specific student submission data they request. This lack of ownership checks can lead to unauthorized access or modification of other users' submissions, violating confidentiality and integrity principles. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no privileges required beyond limited user privileges, no user interaction, and low impact on confidentiality, integrity, and availability. The vulnerability is rated medium severity with a score of 5.3. No patches or known exploits have been published yet, but the risk remains for organizations using this specific version. The vulnerability is particularly concerning for educational institutions managing sensitive student placement data, as unauthorized access could lead to data leakage or manipulation affecting student outcomes or privacy.

For European organizations, especially educational institutions using PlaciPy 1.0.0, this vulnerability could lead to unauthorized access to student placement data, potentially exposing personal information or allowing manipulation of placement records. This could result in privacy violations under GDPR, reputational damage, and loss of trust from students and partners. The integrity of placement decisions could be compromised, affecting students' academic and career prospects. While the vulnerability does not allow full system compromise or denial of service, the unauthorized data access and modification risks are significant in the context of sensitive educational data. Institutions with limited IT security resources may be more vulnerable to exploitation once an exploit becomes available. The lack of known exploits currently reduces immediate risk, but the presence of the vulnerability in a network-accessible service means attackers could exploit it remotely without user interaction, increasing potential impact.

Organizations should immediately audit their PlaciPy deployments to identify if version 1.0.0 is in use. Since no official patch is currently available, a temporary mitigation is to implement additional access control checks at the application or network level, such as restricting access to the student submission routes to trusted IP ranges or VPNs. Developers should modify the backend code to enforce strict object-level authorization by verifying ownership of student submissions before granting access or modification rights. Conduct thorough testing to ensure authorization logic is correctly applied to all relevant endpoints. Additionally, monitor logs for unusual access patterns or attempts to access unauthorized data. Educate users about the risk and encourage reporting of suspicious behavior. Plan for prompt patch deployment once an official fix is released by Praskla-Technology. Consider compensating controls such as data encryption at rest and in transit to reduce data exposure risk.
