CVE-2025-45806 is a cross-site scripting (XSS) vulnerability found in rrweb-snapshot, specifically in versions prior to v2.0.0-alpha.18. This vulnerability allows attackers to execute arbitrary web scripts or HTML through crafted payloads, posing a significant risk to web applications that utilize this component.
The severity of this vulnerability has been classified as medium, with a CVSS score of 6.1. The implications of this vulnerability can expose sensitive information or allow for unauthorized actions on behalf of users, particularly where user interaction is required to trigger the exploit.
Currently, the exploitation status of this vulnerability is not confirmed, and it is awaiting analysis. Therefore, organizations should remain vigilant and prioritize this issue in their patch management strategies.
Organizations should address this vulnerability in their priority patch cycle due to the potential impact on security.
Vulnerability Details
The official description of CVE-2025-45806 states that it is a cross-site scripting (XSS) vulnerability in rrweb-snapshot before v2.0.0-alpha.18. This flaw allows attackers to execute arbitrary web scripts or HTML via a crafted payload.
The CVSS score of this vulnerability is 6.1, indicating a medium severity. The attack vector is classified as NETWORK, with low attack complexity, and no privileges are required. User interaction is necessary, and the vulnerability affects confidentiality and integrity, both rated as low.
This vulnerability is categorized under CWE-79, which pertains to improper neutralization of input during web page generation (XSS).
Technical Analysis
The root cause of this vulnerability lies in the failure to adequately sanitize user input, which allows attackers to inject malicious scripts. The attack vector is network-based, requiring an active user to trigger the malicious payload, thus posing a risk primarily in scenarios where user interaction is expected.
The attack complexity is rated as low, meaning that the exploit can be executed with minimal effort. No privileges are required to exploit this vulnerability, but user interaction is necessary to execute the payload. The potential impacts include low confidentiality and integrity, while availability remains unaffected.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-45806 is significant. If successfully exploited, attackers could execute arbitrary scripts in the context of the affected user's session, leading to data theft or unauthorized actions. Organizations using rrweb-snapshot should assess the potential impact on sensitive data and user trust.
Given the CVSS score of 6.1, organizations should address this vulnerability in their priority patch cycle. The risk of exploitation is increased as it may be leveraged in conjunction with other vulnerabilities or attack vectors.
