CVE-2026-27087 describes a Reflected Cross-Site Scripting (XSS) vulnerability discovered in the Wolverine Framework. This flaw allows attackers to inject malicious scripts into web pages, potentially leading to unauthorized access and data theft. The vulnerability impacts versions 0.0.0 through 1.9 of the Wolverine Framework for WordPress and a fix is pending.
The primary impact of CVE-2026-27087 is the ability for an attacker to execute arbitrary JavaScript code within the context of a user's browser session. This can be exploited to steal sensitive information like cookies, session tokens, and personal data. An attacker could also redirect users to malicious websites, deface the website, or perform actions on behalf of the user without their knowledge. Given the nature of XSS, the blast radius extends to all users who interact with affected pages, potentially impacting a wide range of website visitors.
CVE-2026-27087 was publicly disclosed on 2026-03-25. The vulnerability is a Reflected XSS, which generally means exploitation requires user interaction (e.g., clicking a malicious link). As of this writing, no public proof-of-concept (PoC) code has been released, but the relatively straightforward nature of Reflected XSS suggests that PoCs are likely to emerge. The vulnerability is not currently listed on CISA KEV.
