The Bold Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘percentage’ parameter in all versions up to, and including, 5.4.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The ComboServlet in Liferay Portal 7.4.0 through 7.4.3.111, and older unsupported versions, and Liferay DXP 2023.Q4.0 through 2023.Q4.2, 2023.Q3.1 through 2023.Q3.5, 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions does not limit the number or size of the files it will combine, which allows remote attackers to create very large responses that lead to a denial of service attack via the URL query string.
A relative path traversal vulnerability was discovered in Productivity Suite software version 4.4.1.19. The vulnerability allows an unauthenticated remote attacker to interact with the ProductivityService PLC simulator and delete arbitrary directories on the target machine.
