DescriptionCVE.org

WordPress plugin (Bit Assist) before 1.7.2 is affected by Stored Cross-Site Scripting in Call-To-Action feature. An authenticated attacker with the privileged role (admin) can exploit this to redirect user to malicious site or control the account.

AnalysisAI

Stored Cross-Site Scripting in the Bit Assist WordPress plugin (versions before 1.7.2) allows an authenticated administrator to inject persistent malicious scripts via the Call-To-Action feature. When other users or administrators visit affected pages, the injected payload executes in their browser context, enabling session hijacking, credential theft, or forced redirection to attacker-controlled sites. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold a WordPress administrator role on the target installation - PR:H per the CVSS vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Real-world risk is materially constrained by the PR:H requirement: only users with WordPress administrator role can introduce the stored payload, which limits the practical attacker pool to already-privileged insiders or accounts compromised through separate means. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade Bit Assist to version 1.7.2 or later, which resolves the stored XSS in the Call-To-Action feature. … Detailed patch versions, workarounds, and compensating controls in full report.
