This vulnerability affects versions of the Table of Contents Block from n/a through 1.0.2 and was published on February 24, 2025. The CVSS score assigned to this vulnerability is 6.5, indicating a medium level of severity.
The risk to organizations includes potential unauthorized access to sensitive information, as attackers may leverage this vulnerability to execute arbitrary scripts in the context of the user's browser. Users could be tricked into providing sensitive information that could be used for malicious purposes.
Currently, there is no confirmed public exploit for this vulnerability, and it is not classified as actively exploited. However, the potential for exploitation exists, making it critical for organizations to address this vulnerability in their patch management cycle.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.
Vulnerability Details
The vulnerability is classified as 'Improper Neutralization of Input During Web Page Generation' (CWE-79). It allows for stored XSS attacks, which can be executed when an unsuspecting user accesses a vulnerable page. The CVSS score for this vulnerability is set at 6.5, indicating a medium severity level. This score reflects the risk associated with an attack that can escalate into more serious security incidents.
The affected product is the Achal Jain Table of Contents Block, with versions from n/a to 1.0.2 being vulnerable. The vendor for this product is not specified, but the source of the vulnerability data is Patchstack.
The vulnerability was published on February 24, 2025, and the last modification was made on April 23, 2026.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input during web page generation, which fails to sanitize or validate data properly. This oversight allows attackers to inject malicious scripts, which can be executed in the context of another user's session.
The attack vector is network-based, requiring low attack complexity and low privileges to exploit. User interaction is required as the victim must visit a page that contains the malicious script. The impacts on confidentiality, integrity, and availability are low, but the potential for unauthorized data access is significant.
Risk & Impact Analysis
The real-world risk from CVE-2025-27305 is pertinent, as organizations utilizing the affected version of the Achal Jain Table of Contents Block could face severe consequences if this vulnerability is exploited. The potential for data theft, unauthorized actions performed on behalf of users, and damage to organizational reputation underscores the importance of immediate remediation.
The blast radius of this vulnerability extends to any user of the affected plugin, making it critical for organizations to assess their exposure. Given the CVSS score of 6.5 and the associated risk, organizations should address this vulnerability in their patch cycle.
Organizations should schedule remediation as part of their security best practices to avoid potential exploitation.
