CVE-2026-1891: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in dogrow Simple Football Scoreboard
The Simple Football Scoreboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ytmr_fb_scoreboard' shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2026-1891 is a stored cross-site scripting vulnerability in the Simple Football Scoreboard plugin for WordPress, affecting all versions up to and including 1.0. The issue arises from improper neutralization of input in the 'ytmr_fb_scoreboard' shortcode, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability is classified under CWE-79 and 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).
Potential Impact
An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. This can lead to unauthorized actions performed in the context of other users viewing the page, including partial confidentiality and integrity impacts. There is no indication of availability impact. No known exploits in the wild 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 Simple Football Scoreboard plugin if possible to prevent exploitation.
