User impact: Users encounter slow loading webpages in third-party web browsers if utilizing the web content filtering feature.<\/p>\n

More info: This only occurs for users that are utilizing version 4.18.23050 of Microsoft Defender for Endpoint’s web content filtering feature. Admins can revert build 4.18.23050 of Microsoft Defender for Endpoint to a previous version on behalf of affected users as a work around by following the steps explained in the link below:<\/p>\n

learn.microsoft.com\/en-us\/microsoft-365\/security\/defender-endpoint\/microsoft-defender-antivirus-updates?view=o365-worldwide#how-to-roll-back-an-update<\/a><\/p>\n

Alternatively, admins can change their network protection settings in the Microsoft 365 Defender portal to audit mode to temporarily remediate impact.<\/p>\n

Current status: We’ve identified that a recent Microsoft Defender for Endpoint update introduced a code regression in the web content filtering feature that slows third-party web browsers’ ability to open web pages. We’re creating a code fix to resolve this issue and expect that it will begin deployment by our next scheduled update. We’ll provide a remediation timeline as soon as one becomes available. While waiting for this fix to remediate impact, admins can take the steps outlined in the More info section of this communication as workarounds to mitigate the impact.<\/p>\n

Scope of impact: Any user utilizing version 4.18.23050 of Microsoft Defender for Endpoint’s web content filtering feature is impacted.<\/p>\n

Start time: Wednesday, May 31, 2023, at 12:00 AM UTC<\/p>\n

Root cause: A recent Microsoft Defender for Endpoint update introduced a code regression in the web content filtering feature that slows third-party web browsers’ ability to open web pages.<\/p>\n
