The NMR Strava activities WordPress plugin up to version 1. 0. 14 contains a stored cross-site scripting (XSS) vulnerability in its strava_nmr_connect shortcode. This vulnerability arises from insufficient sanitization and escaping of user-supplied attributes, allowing authenticated users with contributor-level access or higher to inject malicious scripts. These scripts execute when any user views the affected page. The vulnerability has a CVSS score of 6. 4, indicating a medium severity level. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
CVE-2026-5341 is a stored cross-site scripting vulnerability in the NMR Strava activities plugin for WordPress, affecting all versions up to 1.0.14. The issue stems from improper neutralization of input in the strava_nmr_connect shortcode, where user-supplied attributes are not adequately sanitized or escaped. This allows authenticated users with contributor or higher privileges to inject arbitrary web scripts that execute when the page is accessed. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, scope change, and limited confidentiality and integrity impact without availability impact. No patch or official remediation is currently documented.
Potential Impact
An attacker with contributor-level or higher access can inject malicious scripts into pages via the vulnerable shortcode. These scripts execute in the context of users viewing the page, potentially leading to theft of session tokens, defacement, or other client-side impacts. The vulnerability affects confidentiality and integrity but does not impact availability. No known exploits have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the NMR Strava activities plugin if feasible. Monitor official vendor channels for updates and apply any released patches promptly.
