(Security) Improved joining customer messages into conversations on Fetching (Security: GHSA-5jw5-q9j7-4rxc) Improve Helper::getWebCronHash() (Security: GHSA-5jw5-q9j7-4rxc) Escape customer name in the reply_fancy email template (Security) Limit fields which can be populated on mailbox Fetching and Sending settings pages (Security: GHSA-hmqm-33wp-85jj) Require mod_headers (if Apache is used) to download files from /storage/uploads/ (Security: GHSA-w2f5-6wcv-677r) Added CheckBrowser middleware ensuring that browser supports CSP (Security: GHSA-fq98-rxg6-8x4g) Validate host in mail Fetching and Sending settings (Security: GHSA-49pm-xwjj-wvjp) Send emails to all recipients when forwarding to multiple recipients (Security: GHSA-5322) Escape values in Helper::linkify() (Security: GHSA-49pm-xwjj-wvjp) Impact Scope These security vulnerabilities may affect users of , with specific impacts including but not limited to: Attachment token generation algorithm: May lead to forged or tampered attachment tokens. Parameter handling in Ajax actions: May result in unauthorized access or data leakage. String operation errors: May cause application crashes or abnormal behavior. Tags in user names: May lead to cross-site scripting (XSS) attacks. User name escaping when deleting a user: May lead to cross-site scripting (XSS) attacks. Stripping dangerous tags: May lead to cross-site scripting (XSS) attacks. Application of security functions: May result in leakage of security information. Merging customer messages: May cause information leakage or data inconsistency. Improvement of WebCron hash: May allow tampering with scheduled tasks. Customer name escaping: May lead to cross-site scripting (XSS) attacks. Field restrictions on mailbox Fetching and Sending settings pages: May allow unauthorized modifications. File download requirements: May lead to unauthorized file access. Browser CSP support check: May lead to cross-site scripting (XSS) attacks. Mail host validation: May result in unauthorized email sending. Email forwarding: May cause information leakage. Value escaping in Helper::linkify(): May lead to cross-site scripting (XSS) attacks. Remediation Measures To fix the above security vulnerabilities, it is recommended to take the following measures: 1. Update to the latest version: Ensure usage of the latest version of , which already includes the aforementioned security fixes. 2. Check and update dependencies: Ensure all dependencies are up to date, especially those related to security libraries. 3. Review code: Conduct a security review of the code to ensure all user inputs are properly validated and escaped. 4. Enable security middleware: Ensure the middleware is enabled to verify whether the browser supports CSP. 5. Configure server: Ensure correct server configuration, particularly that the Apache server has the module enabled. 6. Regular updates and maintenance: Regularly update and maintain the system to promptly apply the latest security patches.
