CVE-2025-27307 is a medium-severity vulnerability affecting the oooorgle Quotes llama plugin, specifically versions up to and including 3.0.1. This vulnerability allows for Reflected Cross-Site Scripting (XSS), which can be exploited by attackers to inject malicious scripts into web pages viewed by users. Given the widespread use of this plugin in various WordPress installations, the potential for exploitation is significant.
The CVSS score for this vulnerability is 6.5, indicating medium severity. The attack vector is network-based, requiring low complexity and low privileges, with user interaction necessary for exploitation. The vulnerability impacts confidentiality, integrity, and availability, albeit to a low degree.
Organizations should prioritize remediation, as the risk to users includes unauthorized access and potential data manipulation through XSS attacks. Immediate patching of the affected versions is crucial to protect users from these risks.
As of the latest updates, there is no confirmed public exploit available for this vulnerability, but the possibility of future exploitation cannot be dismissed. Therefore, organizations are urged to address this vulnerability promptly.
Vulnerability Details
The vulnerability is characterized as an improper neutralization of input during web page generation, which is classified under CWE-79 for XSS vulnerabilities. It was published on February 24, 2025, and is categorized as deferred in its status.
The affected product, Quotes llama, allows for reflected XSS, which can be triggered when users click on a manipulated link that executes a script in the context of the user's session.
Understanding the attack vector and the implications of this vulnerability is crucial for organizations using this plugin, as it can lead to significant security breaches if not addressed.
Technical Analysis
The root cause of CVE-2025-27307 lies in the plugin's failure to properly sanitize user input before displaying it on web pages. This oversight allows attackers to inject malicious JavaScript into web pages viewed by other users.
The attack vector is primarily network-based, and the complexity of executing an attack is low due to the required privileges being minimal. However, user interaction is necessary, as the victim must click on a crafted link to trigger the XSS.
The impact of this vulnerability is categorized as low for confidentiality, integrity, and availability, meaning that while the risk exists, the potential damage may be limited compared to higher severity vulnerabilities.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized actions performed in the context of a user's session, leading to data exposure or manipulation. The blast radius could extend to any user who interacts with the compromised plugin, thereby affecting a wide user base.
Given that the vulnerability's CVSS score is 6.5, organizations should address it in their priority patch cycle. The potential for exploitation exists, and while currently not actively exploited, organizations should remain vigilant.
The EPSS score of 0.0011 indicates a low probability of exploitation, but this should not deter organizations from applying necessary patches to mitigate any future risks.
