The vulnerability CVE-2025-58873 affects pusheco Pushe Web Push Notification versions up to 0.5.0 and involves improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). This allows an attacker with high privileges and requiring user interaction to inject malicious scripts that can execute in the context of other users. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and impacts on confidentiality, integrity, and availability at a low level. There is no vendor advisory or patch information available at this time.

Successful exploitation of this stored XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of users of the Pushe Web Push Notification application, potentially leading to limited disclosure of information, modification of data, or disruption of service. The attack requires high privileges and user interaction, which reduces the likelihood and impact severity. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with input handling and consider applying any available workarounds or input sanitization controls. Monitor official pusheco communications for updates regarding patches or mitigations.
