An open redirect vulnerability in Frontend Post Submission Manager Lite allows unauthenticated attackers to manipulate URL redirects. This vulnerability can be exploited via insufficient validation of the 'requested_page' POST parameter, enabling unauthorized redirects. The impact includes potential phishing and exposure to malicious sites if users are tricked into clicking deceptive links. Such redirection flaws are often exploited in social engineering attacks. It's crucial to address this to prevent unauthorized redirections to harmful destinations. The CVE-2026-1296 reference provides further details on this vulnerability.
The open redirect issue in Frontend Post Submission Manager Lite arises from improper validation of the 'requested_page' parameter. The vulnerability can be triggered via HTTP POST requests, specifically targeting the /wp-login.php endpoint. Attackers craft requests directing users to arbitrary destinations, leveraging the insufficient handling of input parameters. The HTTP status code 302 response signals a redirection, which can be checked by analyzing response headers. Exploiting this allows attackers to redirect genuine users to malicious sites without authorization. Monitoring and filtering parameter values can mitigate this risk.
Exploitation of this vulnerability can lead to end-users being redirected to phishing sites or other malicious pages. This poses risks such as credential theft, exposure to malware, and loss of sensitive data. Attackers can gain trust under false pretenses, potentially accessing personal or financial information. The redirection exploits might further facilitate larger-scale attacks by amassing victim data through bait sites. Prompt remediation reduces the risk of users being deceived into interacting with unauthorized resources, preserving user trust and site integrity.
