Action Required: Preparation for January 2026 Tenable Security Center Feed Update
We are writing to announce an important upcoming change to the Tenable Security Center feed data. Starting in mid-January 2026, the size of Tenable Security Center feeds will increase due to the addition of new Vulnerability Priority Rating (VPR) data; this data will be available in Tenable Security Center 6.8, anticipated for release later in Q1 2026. This update ensures you continue to receive comprehensive vulnerability data, but it requires immediate action to ensure your environment is prepared. What you need to do To prevent the feed size from causing PHP memory exhaustion in your environment, please follow the resolution path for your specific version: Versions 6.5.1 – 6.7.2: Patch 202601.1 is now available. Applying this patch will automatically modify the PHP configuration to increase the memory limit. Versions Prior to 6.5.1: Follow the instructions outlined in this Knowledge Base article to modify the PHP configuration. Note: Tenable Security Center consoles with less than 8 GB RAM may need to have their hardware resources updated. Review Tenable Security Center hardware recommendations Why this matters Taking action now allows you to adopt a proactive approach to this feed expansion, ensuring your nightly updates continue seamlessly. Prevent SC Feed Update Failures: Without this fix, SC Feed updates may fail and log an "Allowed memory size... exhausted" error or terminate abnormally with error status '255'. Protect Disk Space: Failing feed updates can leave behind orphaned files in /opt/sc/data/feed.XXXXX folders, which may build up and cause disk space issues over time.
