CVE-2025-26779 is classified as a path traversal vulnerability affecting the Keep Backup Daily plugin developed by Fahad Mahmood. This vulnerability allows attackers to exploit the improper limitation of a pathname to a restricted directory, potentially leading to unauthorized access to sensitive files. The severity of this vulnerability is rated as medium, with a CVSS score of 4.9, indicating that while it poses a risk, it is not as critical as higher-severity vulnerabilities.
Organizations utilizing the Keep Backup Daily plugin, particularly versions up to and including 2.1.0, should prioritize patching this vulnerability. Exploitation of this vulnerability could lead to significant data exposure, especially in environments where sensitive files can be accessed through the plugin's functionality.
Currently, there are no known public exploits or proof-of-concept code available for this vulnerability. However, it is crucial for organizations to remain vigilant, as the potential for exploitation exists if attackers discover a method to leverage this flaw.
Organizations should act quickly to mitigate the risks associated with this vulnerability by implementing available patches and updates to the affected software. Immediate attention to this issue is recommended to prevent potential unauthorized access.
Vulnerability Details
The vulnerability described in CVE-2025-26779 arises from an improper limitation of a pathname to a restricted directory, known as path traversal. The affected software, Keep Backup Daily, allows unauthorized file access due to this vulnerability. The CVSS score of 4.9 indicates a medium severity level, with a high confidentiality impact but no integrity or availability impact.
This vulnerability affects all versions of Keep Backup Daily up to 2.1.0, and it is classified under CWE-22, which pertains to path traversal vulnerabilities.
The vulnerability was published on February 16, 2025, and is currently marked as deferred, indicating that it may not yet have an available patch.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of user-supplied input, specifically the handling of file paths. The attack vector for this vulnerability is network-based, allowing attackers to exploit it remotely. The attack complexity is low, meaning that it can be easily executed by an attacker with high privileges, as no user interaction is required.
Given that the attacker requires high privileges, this may limit the potential exploitability to users already having access to the system. However, the high confidentiality impact indicates that sensitive information could be exposed if the vulnerability is successfully exploited.
Risk & Impact Analysis
Risk to organizations includes exposure of sensitive files, which could lead to significant data breaches. The potential blast radius is considerable, especially for organizations that handle sensitive customer data. Although this vulnerability does not currently appear in the Known Exploited Vulnerabilities (KEV) catalog, its medium CVSS score signifies that organizations should assess their risk based on the potential for exploitation.
Given the low EPSS score of 0.00114, the likelihood of exploitation is statistically low; however, organizations should not treat this vulnerability as negligible. Continuous monitoring and patching of the affected software are essential to mitigate risks.
Exploitation Status
Signal | Status |
|---|---|

Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of Keep Backup Daily are all versions prior to vendor patch, specifically from n/a through <= 2.1.0. Organizations should confirm their installed versions and ensure they are updated to the latest release.
Mitigation & Remediation
Organizations are advised to monitor for updates related to CVE-2025-26779. Immediate patching is necessary to eliminate the path traversal risk. If a patch is not available, organizations should consider disabling the Keep Backup Daily plugin until a fix can be applied. Additionally, implementing strong access controls and monitoring logs for unusual access patterns can help reduce the risk of exploitation.
For comprehensive security testing, organizations can leverage penetration testing services to identify potential vulnerabilities in their systems.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor for unusual file access patterns and review logs for any unauthorized access attempts. Additionally, security teams should look for signs of path traversal attempts within application logs and implement alerts for suspicious file access requests.
