Summary
Katie Seaborn's Zotpress WordPress plugin, versions through 7.4.4, contains a stored cross-site scripting flaw (CWE-79). Input is not neutralized when web pages are generated, so injected script is stored and runs in other users' browsers. A remote attacker with low privileges needs a user to interact with the affected page for the attack to succeed.
