Users of the All in One SEO Pack are being told to update to the latest version of the popular WordPress plugin because researchers with web monitoring and malware clean up service Sucuri uncovered two vulnerabilities last week during an audit of the code.
A privilege escalation flaw could enable a user without administrative privileges – such as an author or subscriber – to make modifications, including to SEO title, description and keyword meta tags, according to a Saturday post by Marc-Alexandre Montpas, an analyst with Sucuri.
The privilege escalation bug could be used with a second flaw that enables execution of malicious Javascript code on an administrator's control panel, meaning attackers could change administrator account passwords and even open some backdoors for easier access in the future, according to the post.
