CVE-2025-53291 is a security vulnerability classified under CWE-862 (Missing Authorization) affecting the product Spreadconnect developed by spoddev2021. This vulnerability exists in versions up to 2.1.5, though the exact affected versions are not explicitly detailed. The core issue is that the application fails to properly enforce authorization checks, allowing an attacker with some level of privileges (PR:L - privileges required: low) to perform unauthorized actions. According to the CVSS 3.1 vector, the attack can be executed remotely over the network (AV:N) with low attack complexity (AC:L), does not require user interaction (UI:N), and affects the integrity and availability of the system (I:L, A:L) but not confidentiality (C:N). This means an attacker can potentially alter data or disrupt services without needing to trick a user or have high privileges, but cannot directly access confidential information. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability’s medium severity rating (CVSS score 5.4) reflects the moderate risk posed by unauthorized modification or disruption of system functions due to missing authorization controls. The vulnerability is significant because missing authorization can lead to privilege escalation or unauthorized operations, which can be leveraged for further attacks or service disruption.

For European organizations using Spreadconnect, this vulnerability could lead to unauthorized modification or disruption of critical business processes managed through the software. Since the vulnerability allows low-privilege users to perform unauthorized actions remotely without user interaction, attackers could exploit this to alter data integrity or availability, potentially causing operational downtime or data corruption. This could impact sectors relying on Spreadconnect for connectivity or integration tasks, including manufacturing, logistics, or enterprise IT environments. The absence of confidentiality impact reduces the risk of data leaks but does not eliminate the risk of sabotage or service interruption. Given the medium severity, organizations might face moderate operational and reputational damage if exploited, especially if Spreadconnect is integrated into critical infrastructure or business workflows. The lack of known exploits suggests a window for proactive mitigation before widespread attacks occur.

1. Immediate mitigation should include restricting network access to Spreadconnect services to trusted internal networks or VPNs to reduce exposure to remote attackers. 2. Implement strict access control policies ensuring that users have only the minimum necessary privileges, as the vulnerability requires low privileges to exploit. 3. Monitor logs and system behavior for unusual activities indicative of unauthorized actions or integrity violations. 4. Engage with spoddev2021 or official channels to obtain and apply patches or updates as soon as they become available. 5. Conduct a thorough review of authorization mechanisms within Spreadconnect configurations and workflows to identify and remediate any missing or weak authorization checks. 6. Consider deploying Web Application Firewalls (WAFs) or Intrusion Detection/Prevention Systems (IDS/IPS) with custom rules targeting suspicious requests to Spreadconnect endpoints. 7. Educate internal users about the importance of safeguarding credentials and promptly reporting anomalies.
