CVE-2025-47455 is a medium-severity security vulnerability classified as CWE-601, commonly known as an 'Open Redirect' vulnerability, found in the CRM Perks Integration plugin for WooCommerce and Salesforce. This integration plugin facilitates data synchronization and workflow automation between WooCommerce e-commerce platforms and Salesforce CRM systems. The vulnerability affects versions up to 1.7.5 and allows an attacker to craft malicious URLs that redirect users to untrusted external websites. Specifically, the flaw arises because the plugin does not properly validate or restrict URL parameters used for redirection, enabling attackers to exploit this behavior for phishing attacks. When a user clicks a manipulated link, they are redirected to a malicious site that may impersonate legitimate services, potentially leading to credential theft or malware distribution. The CVSS 3.1 base score is 4.7 (medium), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact on confidentiality is low (C:L), with no impact on integrity or availability. The vulnerability scope is changed (S:C) because the redirection can lead users outside the trusted domain. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on May 7, 2025, and is tracked by Patchstack and CISA enrichment. This vulnerability primarily facilitates phishing by leveraging trusted brand names and legitimate-looking URLs, increasing the likelihood of successful social engineering attacks.

For European organizations using the CRM Perks Integration plugin with WooCommerce and Salesforce, this vulnerability poses a significant phishing risk. Attackers can exploit the open redirect to craft convincing phishing campaigns that redirect employees or customers to malicious sites, potentially leading to credential compromise or malware infections. Given the widespread use of WooCommerce and Salesforce in European e-commerce and customer management sectors, this vulnerability could undermine trust in affected businesses and lead to data breaches indirectly through social engineering. The vulnerability does not directly compromise system integrity or availability but can be a stepping stone for further attacks if credentials are stolen. Organizations handling sensitive customer data or operating in regulated sectors such as finance, healthcare, or retail may face compliance risks if phishing leads to data exposure. Additionally, the cross-domain redirection could be abused in multi-tenant environments or cloud deployments common in Europe, increasing the attack surface. The medium severity score suggests that while the vulnerability is not critical, it should be addressed promptly to prevent exploitation in phishing campaigns, which remain a top cyber threat vector in Europe.

1. Immediate mitigation involves applying any available patches or updates from CRM Perks once released; monitor vendor advisories closely. 2. In the absence of patches, implement strict URL validation and sanitization on the integration endpoints to restrict redirection targets to trusted domains only. 3. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious redirection attempts or malformed URLs targeting the vulnerable plugin. 4. Educate employees and customers about phishing risks, emphasizing caution with links, especially those involving CRM Perks or WooCommerce-related URLs. 5. Use multi-factor authentication (MFA) for Salesforce and WooCommerce accounts to reduce the impact of credential theft. 6. Monitor logs for unusual redirection patterns or spikes in user complaints related to phishing. 7. Consider implementing Content Security Policy (CSP) headers to restrict allowable redirection and framing behaviors. 8. Conduct regular security assessments and penetration testing focusing on integration points between WooCommerce and Salesforce to identify similar issues proactively.
