CVE-2026-28078 is classified as a medium severity vulnerability affecting the Stylemix uListing plugin. This vulnerability allows improper limitation of a pathname to a restricted directory, also known as a path traversal vulnerability. The affected versions of uListing are from n/a through version 2.2.0. Given its CVSS score of 4.9, this vulnerability poses a notable risk to organizations utilizing this plugin.
Risk to organizations includes potential unauthorized access to sensitive files on the server, which could lead to data exposure. Attackers can exploit this vulnerability through network access, and its low attack complexity enhances the risk, necessitating immediate attention from security teams.
Organizations should prioritize patching immediately. As of now, there is no public exploit confirmed for this vulnerability, but the exploitation status is deferred, indicating that it requires urgent consideration.
Given the potential impacts, organizations using the uListing plugin should remain vigilant and prepare to implement necessary updates or mitigations.
Vulnerability Details
The vulnerability is characterized as a path traversal issue, which allows attackers to access files outside the intended directory. The CVSS 3.1 score of 4.9 indicates a medium severity level, suggesting that while it is not the most critical, it still poses a significant risk.
The vulnerability impacts the Stylemix uListing plugin, with the last published version being 2.2.0, and was first disclosed on March 5, 2026. The CWE classification for this vulnerability is CWE-22.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of user input, which allows attackers to manipulate file paths. The attack vector is network-based, and the attack complexity is classified as low, requiring high privileges but no user interaction.
The impacts include high confidentiality risk, as access to sensitive files can be obtained. There is no impact on integrity or availability, making this vulnerability primarily a confidentiality concern.
Risk & Impact Analysis
Organizations using the uListing plugin face real-world risks, particularly if sensitive data is stored on the server. The blast radius could extend across multiple user accounts if exploited, leading to widespread data exposure.
With an EPSS score indicating a low likelihood of exploitation, organizations should still remain proactive in addressing this vulnerability due to its potential impacts.
Exploitation Status
Signal | Status |
|---|---|
