The vulnerability CVE-2025-32528 affects maximevalette iCal Feeds (<= 1.5.3) and is classified as a reflected Cross-site Scripting (XSS) issue. It occurs due to improper neutralization of input during web page generation, enabling attackers to inject malicious scripts that execute when a user interacts with a crafted URL or input. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, and impacts on confidentiality, integrity, and availability with scope change.

Successful exploitation of this vulnerability can allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability of user data. The scope of impact extends beyond the vulnerable component due to the reflected nature of the XSS.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, users should exercise caution when interacting with untrusted input or URLs related to iCal Feeds. Implementing web application firewall (WAF) rules to detect and block reflected XSS attempts may provide temporary mitigation.
