CVE-2023-4961 is a vulnerability affecting the Poptin plugin for WordPress in versions up to and including 1.3. It is categorized as a Stored Cross-Site Scripting vulnerability, allowing authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts through the 'poptin-form' shortcode. This vulnerability arises due to insufficient input sanitization and output escaping on user-supplied attributes. The affected products include various versions of t0V6Qc, t0V6Qd, t0V6Qe, t0V6Qf, t0V6Qb, t0V6Qk, t0V6Ql, t0V6Qm, t0V6Qn, t0V6Qg, t0V6Qh, t0V6Qi, and t0V6Qj. The potential danger to organizations lies in the execution of arbitrary web scripts whenever a user accesses an injected page. To remediate this vulnerability, it is recommended to update the Poptin plugin for WordPress to a version beyond 1.3 that addresses the insufficient input sanitization and output escaping issue.
