Adobe's last scheduled security update of the year has resolved critical vulnerabilities in Lightroom, Prelude, and Experience Manager. 

Released on Tuesday, the tech giant's patches deal with four vulnerabilities, three of which are deemed critical. 

The first fix was issued for Adobe Lightroom, image editing software that is popular with professional photographers. Impacting Lightroom Classic version 10.0 and below on Windows and macOS machines, the critical issue -- tracked as CVE-2020-24447 -- is described as an uncontrolled search path element vulnerability leading to arbitrary code execution.

A second critical bug was found in Adobe Prelude  for Windows and macOS, version 9.01 and earlier. Tracked as CVE-2020-24440, the severe vulnerability has been caused by an uncontrolled search path and if exploited by attackers, can lead to "arbitrary code execution in the context of the current user," according to Adobe. 

Adobe's third security advisory relates to Adobe Experience Manager (AEM) and the AEM Forms add-on package on all platforms. 

Two vulnerabilities have been patched in these software packages. The first, CVE-2020-24445, is a critical bug in AEM CS, and is also found in AEM and earlier. 

CVE-2020-24445 is a stored cross-site scripting (XSS) flaw that can lead to arbitrary JavaScript execution in the browser.
