Deeper analysis

CVE-2025-23977 is a Cross-Site Request Forgery (CSRF) vulnerability, classified under CWE-352, in the Bhaskar Dhote Post Carousel Slider WordPress plugin (post-carousel-slider) that enables Stored XSS. The vulnerability affects all versions from n/a through 2.0.1 and was published on 2025-01-31. It carries a CVSS v3.1 base score of 7.1 (High), with vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L.

The vulnerability can be exploited by any network-accessible attacker with low attack complexity, requiring no privileges but relying on user interaction, such as tricking an authenticated user into performing a malicious request. Exploitation changes the scope (S:C), allowing attackers to inject and store XSS payloads via CSRF, which can then execute in the context of other users viewing affected content, leading to low-level impacts on confidentiality, integrity, and availability.

prevent

SC-23 requires mechanisms like CSRF tokens to protect session authenticity, directly preventing forged requests that exploit this CSRF vulnerability leading to stored XSS.

prevent

SI-10 enforces input validation to reject malicious XSS payloads that could be stored via the CSRF attack in the Post Carousel Slider plugin.

prevent

SI-15 applies output filtering and encoding to neutralize stored XSS payloads when affected carousel content is rendered for other users.
