CVE-2025-26876 is a Path Traversal vulnerability (CWE-35) identified in the CodeManas product 'Search with Typesense' affecting versions up to 2.0.8. Path Traversal vulnerabilities occur when an application improperly sanitizes user-supplied input used to construct file or directory paths, allowing attackers to access files and directories outside the intended scope. In this case, the vulnerability allows an attacker to manipulate file paths to access unauthorized files on the server hosting the Search with Typesense application. The CVSS v3.1 base score is 6.8, indicating a medium severity level. The vector string (AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H) reveals that the attack can be executed remotely over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact is specifically on availability (A:H), with no confidentiality or integrity impact. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability could allow a privileged attacker to cause denial of service or disrupt the availability of the Search with Typesense service by accessing or manipulating critical files or directories through path traversal. Since the vulnerability requires high privileges, it is likely exploitable only by authenticated users with elevated access, limiting the attack surface but still posing a significant risk if such credentials are compromised or misused.

For European organizations using CodeManas Search with Typesense, this vulnerability could lead to service disruption or denial of service conditions, impacting business operations reliant on search functionality. Since the vulnerability affects availability and requires high privilege, the primary risk is from insider threats or attackers who have already gained elevated access. This could result in downtime, loss of productivity, and potential reputational damage. Organizations in sectors where search services are critical, such as e-commerce, digital libraries, or enterprise knowledge management, may experience operational impacts. Additionally, disruption of search services could indirectly affect customer experience and internal workflows. The lack of confidentiality and integrity impact reduces the risk of data breaches or data tampering, but availability issues can still have significant operational consequences. The absence of known exploits in the wild provides a window for organizations to proactively address the vulnerability before active exploitation occurs.

1. Restrict access to the Search with Typesense application to only trusted and necessary users, enforcing the principle of least privilege to minimize the number of users with high-level privileges. 2. Implement strict input validation and sanitization on all user-supplied path parameters to prevent traversal sequences such as '../' or '..\'. 3. Monitor and audit privileged user activities to detect any anomalous behavior that could indicate attempts to exploit path traversal. 4. Deploy application-layer firewalls or runtime application self-protection (RASP) solutions capable of detecting and blocking path traversal attempts. 5. Segregate the Search with Typesense service in a secure network segment with limited access to critical file systems. 6. Apply any available patches or updates from CodeManas promptly once released. 7. Conduct regular security assessments and penetration testing focusing on file path handling and privilege escalation scenarios. 8. Educate administrators and privileged users on the risks of credential compromise and enforce multi-factor authentication to reduce the risk of unauthorized access.
