WordPress Core Update RCE Vulnerability CVE-2026-119977 Actively Exploited, CISA Adds to KEV Catalog
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical remote code execution flaw in WordPress to its Known Exploited Vulnerabilities catalog after confirming active exploitation in the wild. The vulnerability, tracked as CVE-2026-119977, resides in the core update mechanism and allows attackers to predict temporary file paths created during package updates, enabling unauthorized code execution from external sources. Wordfence assigned the flaw a CVSS v3.1 base score of 8.1 and reported blocking over 13,000 exploitation attempts targeting its customers within a single 24-hour period. The issue was addressed in the WordPress 7.1.4 release on October 28, 2026, with backports now being rolled out to all branches from version 4.7 onward. CISA has set a three-day remediation deadline of November 6, 2026, for U.S. federal agencies and instructed them to investigate potential compromises. Security researchers note that the attack leverages predictable temporary file locations during the update process, making it particularly dangerous for unpatched installations.

Google Releases November Android Security Patch Fixing 216 Vulnerabilities Including Critical Zero-Click Flaws
Google has issued its November security update for Android, addressing a total of 216 vulnerabilities with 23 classified as critical. The patch resolves multiple remote code execution flaws that require no additional privileges or user interaction, qualifying as zero-click attacks. Specific fixes include CVE-2026-58868 in the Framework component and CVE-2026-58876 along with CVE-2026-58936 in the System component, all impacting Android versions 14 through 17. Additional patches cover privilege escalation, information disclosure, and denial-of-service issues across the kernel, Bluetooth, virtualization layers, and chipsets from MediaTek and Qualcomm. No evidence of in-the-wild exploitation has been noted in the bulletin, yet the critical nature of the remote code execution bugs warrants immediate attention. Users must verify the 2026-11-05 patch level or newer in device settings, as simply running the latest Android version does not guarantee all fixes are installed. Some updates arrive via Google Play system updates while others depend on device manufacturers.
