The vulnerability identified as CVE-2025-23700 is classified as a high-severity Cross-site Scripting (XSS) issue within the yonisink yCyclista plugin, allowing for reflected XSS attacks. This vulnerability affects versions up to and including 1.2.3.
With a CVSS score of 7.1, the severity of this vulnerability indicates that it poses significant risk to organizations using the affected plugin. Exploitation of this flaw could lead to unauthorized actions being executed within the context of the user's session.
The exploitation status of this vulnerability is currently deferred, meaning it has not been confirmed to be actively exploited in the wild. However, organizations should remain vigilant as the potential for exploitation remains.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.
Vulnerability Details
The vulnerability allows improper neutralization of input during web page generation, specifically resulting in reflected XSS. The vulnerability is classified under CWE-79, indicating it is related to improper neutralization of input. The affected versions are those up to 1.2.3, and the issue was published on January 22, 2025.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation and sanitization of user inputs, allowing attackers to inject malicious scripts that can be executed in the context of the user’s browser.
The attack vector for this vulnerability is network-based, requiring low complexity and no privileges for the attacker. User interaction is required to trigger the vulnerability, as the malicious script must be executed by the user's browser.
The impacts of this vulnerability are of low confidentiality, integrity, and availability. Should an attack succeed, attackers may leverage it to execute arbitrary scripts in the user's session, potentially leading to unauthorized information disclosure.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized actions executed within a user’s session, leading to data exposure or manipulation. The blast radius could impact all users of the affected plugin. Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle.
Additionally, it is crucial to consider the low EPSS score of 0.00346, indicating a lower likelihood of exploitation in the wild, yet vigilance is advised due to the nature of XSS vulnerabilities.
