The vulnerability CVE-2025-26998 in sonalsinha21 SKT Blocks plugin allows stored cross-site scripting due to improper input neutralization during web page generation. This enables an attacker with low privileges to inject malicious scripts that execute in the context of other users, potentially leading to partial confidentiality, integrity, and availability impacts. The affected versions are up to 1.8 inclusive. No patch or remediation details are provided in the available data.

Successful exploitation of this stored XSS vulnerability can lead to partial compromise of confidentiality, integrity, and availability of affected systems or user data. Attackers may execute arbitrary scripts in the context of other users, potentially stealing session tokens or performing unauthorized actions. However, the attack requires user interaction and low privileges, limiting the scope and impact compared to higher severity vulnerabilities.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting privileges for users who can input data into SKT Blocks and apply web application firewall (WAF) rules to detect and block XSS payloads. Monitor vendor channels for updates regarding patches or official mitigations.
