Activision Deploys Steam Security Update for WWII and Black Ops 3

Activision has deployed a security update for the Steam versions of Call of Duty: Black Ops 3 and Call of Duty: WWII, and the official Call of Duty Updates account recommended players update for recent improvements. The publisher’s action targets the two legacy PC titles on Steam and was reported alongside notices from community outlets.

The deployment is dated March 1, 2026 in reporting compiled for this story. The Call of Duty Updates account is referenced in announcements; a preserved post fragment reads "@CODUpdates: We've released a security update for the Steam versions of Call of Duty: WWII and Call of Duty: Black Ops 3 as part of our ongoing" and the original report summarized the publisher message: "Activision has deployed a security update for the Steam versions of Call of Duty: Black Ops 3 and WWII, confirming ongoing support for legacy titles. The official Call of Duty Updates account recommends players update for recent improvements. CoD news outlets like Charlie INTEL and ModernWarzone hig"

The original report explicitly interprets the deployment as confirmation of continued attention to older entries in the franchise, stating the update "confirms ongoing support for legacy titles." Community-facing outlets Charlie INTEL and ModernWarzone are named in the reporting as having mentioned the update, though their specific writeups or additional technical details were not included in the supplied material.

Key technical details are not present in the announcement fragments: no patch notes or changelog entries were provided, no CVE or vulnerability identifiers were listed, no build or version numbers were supplied, and the size of the download and region or phased rollout information were not reported. The announcement fragments also stop mid-sentence, leaving the phrase "as part of our ongoing" incomplete and without clarification of the program or schedule referenced.

Players and server operators should note that the only explicit recommendation in the available material is to install the update for "recent improvements," attributed to the Call of Duty Updates account. Activision has not, in the supplied text, published detailed notes on what the security update addresses, whether installation is mandatory, or whether the fix affects consoles or storefronts beyond Steam.

Until a full statement or Steam news entries appear from Activision or the Call of Duty Updates account, the concrete facts remain: Activision pushed a security update for the Steam versions of Call of Duty: Black Ops 3 and Call of Duty: WWII, the Call of Duty Updates account posted a brief notice beginning "We've released a security update..." and reporting outlets Charlie INTEL and ModernWarzone were cited as having covered the news. Further technical details and official patch notes are pending from Activision.
