CVE-2004-0380
HighSummary
The MHTML protocol handler in Microsoft Outlook Express 5.5 SP2 through Outlook Express 6 SP1 allows remote attackers to bypass domain restrictions and execute arbitrary code. This is demonstrated using a script in a compiled help (CHM) file that references InfoTech Storage (ITS) protocol handlers.
Risk Assessment
Attackers can exploit this vulnerability to execute malicious code on user systems, potentially leading to data loss or system takeover.
Recommendation
It is recommended to update Microsoft Outlook Express to the latest version and implement appropriate security measures to mitigate the risk of this vulnerability.

The SigmaForms Pro – AI Generated Forms plugin for WordPress up to version 1.4.11 is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_submission_files function. Unauthenticated attackers can delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The malicious path traversal URL is submitted via form upload field and stored in the database, with deletion triggered when an administrator deletes the submission record from the admin panel.

The Booking for Appointments and Events Calendar – Amelia (Premium) plugin for WordPress versions 8.0 - 9.6.2 is vulnerable to privilege escalation due to insufficient validation of the 'type' parameter in the customer update endpoint. This allows customers to set their role to 'manager' and trigger creation of a WordPress user with the wpamelia-manager role when 'externalId' is set to 0. Unauthenticated attackers can escalate to administrator by first elevating to manager, then creating a provider entity linked to an administrator user ID and overwriting that administrator's password.

- CVE-2026-84480Critical
WWBN AVideo fails to validate password recovery token expiration in userRecoverPassSave.json.php, allowing attackers to use expired tokens to reset account passwords indefinitely. Attackers who obtain a recovery token can use it at any time to change the target account's password and gain full account access.
- CVE-2026-84479Critical
WWBN AVideo (current e01e41ecc and earlier) makes three login-time security controls depend solely on the client-supplied User-Agent header. The isAVideoEncoder()/isAVideoMobileApp() checks match HTTP_USER_AGENT against a hardcoded literal ("AVideoEncoder"/"AVideoMobileApp") with no IP check or shared secret. An attacker who submits valid credentials and sets User-Agent: AVideoEncoder bypasses two-factor authentication, skips brute-force captcha escalation, and avoids being recorded in the login/device audit history. No patch is available at the time of publication.
