Unauthenticated Cross Site Scripting (XSS) in Kapee < 1.7.1 versions.

AnalysisAI

Reflected/stored cross-site scripting in the Kapee WordPress theme versions prior to 1.7.1 allows remote unauthenticated attackers to inject arbitrary script that executes in a victim's browser after user interaction, with a scope change that can impact other components beyond the vulnerable theme. No public exploit identified at time of analysis, but the vulnerability was disclosed via Patchstack with a CVSS of 7.1, reflecting the unauthenticated nature combined with required user interaction.

Vulnerability AssessmentAI

Exploitation Exploitation requires (1) a target site running the Kapee WordPress theme at a version below 1.7.1, (2) a victim - typically a logged-in WordPress user, ideally an administrator - to interact with attacker-supplied content such as clicking a crafted URL or visiting a page containing injected content (UI:R in the CVSS vector), and (3) network reachability to the vulnerable WordPress site. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L scores 7.1, elevated primarily by the scope change (S:C) - indicating injected script can affect resources beyond the vulnerable component (e.g., the WordPress admin session or other site origins). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a URL targeting a vulnerable Kapee theme endpoint (for example, a search or product parameter) containing a JavaScript payload, then phishes the link to a site administrator via email or social media. When the administrator clicks the link while authenticated, the script executes in the admin's browser context and, due to the scope change, can hijack the WordPress session, create rogue admin accounts, or plant persistent backdoors.
Remediation Upgrade the Kapee theme to version 1.7.1 or later, which is the fixed release per Patchstack's advisory at https://patchstack.com/database/wordpress/theme/kapee/vulnerability/wordpress-kapee-theme-1-7-1-cross-site-scripting-xss-vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report.
