CVE-2026-28275 is identified as a high-severity vulnerability affecting the Morelitea Initiative platform, a self-hosted project management tool. This vulnerability allows access through previously issued JWT access tokens even after users change their passwords. The flaw is particularly concerning as it allows ongoing authenticated access to protected API endpoints until the token expires, posing a significant risk to user accounts and sensitive data.
With a CVSS score of 8.1, this vulnerability is classified as high severity, emphasizing the critical need for organizations using the Initiative platform to prioritize patching. The release of version 0.32.4 addresses this issue by ensuring that JWT tokens are invalidated upon password changes.
Risk to organizations includes potential unauthorized access to sensitive data and functionalities. Given the exploitability of this vulnerability, organizations must act quickly to mitigate risks associated with the continued validity of old tokens.
Organizations should prioritize patching immediately. Staying ahead of vulnerabilities like CVE-2026-28275 is essential for maintaining the security of user accounts and protecting organizational assets.
Vulnerability Details
The vulnerability allows attackers to exploit the issue by reusing valid JWT tokens that should have been invalidated after a password change. Specifically, versions of the Initiative application before 0.32.4 do not properly invalidate these tokens, leading to significant security risks.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N, indicating high confidentiality and integrity impacts with a low attack complexity, allowing attackers with low privileges to exploit the vulnerability without user interaction.
The vulnerability is associated with CWE-613, which pertains to the improper session invalidation, highlighting the importance of session management in application security.
Technical Analysis
Root cause of CVE-2026-28275 lies in the implementation of JWT token management within the Initiative platform. When a user changes their password, the system fails to invalidate previously issued tokens, allowing those tokens to remain valid until their expiration.
The attack vector is network-based, meaning that an attacker could exploit this vulnerability over the internet. Attack complexity is low, as no advanced skills are required to utilize valid tokens for unauthorized access.
Privileges required for exploitation are low, as an attacker only needs access to a valid token. User interaction is not required, making it easier for attackers to exploit this vulnerability without needing user consent.
The impacts of this vulnerability are severe, as it affects both confidentiality and integrity. An attacker could potentially access sensitive data and perform actions on behalf of the user, thereby compromising the integrity of user accounts.
Risk & Impact Analysis
Real-world deployment risk for organizations using the Initiative platform is significant. With the potential for unauthorized access to sensitive data, organizations could face severe consequences including data breaches and regulatory penalties.
Why this matters to organizations is highlighted by the critical nature of password management and session invalidation. If older tokens remain valid, organizations are at risk of exploitation, leading to possible unauthorized actions carried out by attackers using those tokens.
The blast radius of this vulnerability is high due to the potential for widespread access to sensitive API endpoints. Organizations relying on the Initiative platform for project management must address this vulnerability swiftly to mitigate the risk of exploitation.
Given the CVSS score of 8.1 and the lack of known exploits, organizations should address this vulnerability in their priority patch cycle. The urgency for remediation is high, as failure to patch could lead to serious security incidents.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to 0.32.4 of the Initiative platform are affected by this vulnerability. Organizations should ensure they are upgraded to the fixed version 0.32.4 to mitigate the associated risks.
Mitigation & Remediation
To remediate CVE-2026-28275, organizations must upgrade to version 0.32.4 of the Initiative platform, which resolves the token invalidation issue. Patching should be prioritized to prevent potential unauthorized access.
In scenarios where a patch cannot be immediately applied, organizations should consider implementing additional security measures, such as enhanced monitoring of API access and sessions management to help mitigate risks.
For further guidance, organizations can refer to our penetration testing methodology to assess their security posture.
Detection Guidance
Organizations should monitor logs for indicators of unauthorized access attempts utilizing older JWT tokens. Additionally, behavioral anomalies such as unusual access patterns to protected API endpoints should be flagged for review.
Network signatures for any unauthorized access using expired tokens should be established to help in early detection of potential exploitation attempts.
AppSecure Threat Intelligence Insight
