- Academic researchers have released details about a new attack method they call “Trojan Source” that allows injecting vulnerabilities into the source code of a software project in a way that human reviewers can’t detect. The researchers showed that one way this can be achieved is by using Unicode controls for bidirectional text (e.g. LRI -left-to-right isolate, and RLI -right-to-left isolate) to dictate the direction in which the content is displayed. This method is now tracked as CVE-2021-42574.

- CISA issued a new directive that forces federal civilian agencies to remediate at least 306 vulnerabilities commonly exploited during attacks. CISA officials emphasized that the catalog was focused on vulnerabilities they said were “causing harm now” but would also be used as a running list of prioritized vulnerabilities based on their evolving understanding of adversary activity.
- A Zero-Day vulnerability has been identified by the Massachusetts-based cybersecurity firm Randori in Palo Alto Networks firewalls using GlobalProtect VPN.
