    Snipe-IT before 8.6.3: deactivated users can sign back in via Google SSO (CVE-2026-116199)

    A newly published CVE (CVE-2026-116199, assigned by VulnCheck on Oct 25) covers a flaw in Snipe-IT's Google SSO login. Versions before 8.6.3 didn't check whether an account was deactivated, so a former user whose Google account was still active could sign back in with their old permissions, including admin. It only applies when Google SSO is on and usernames are email addresses, and Snipe-IT says default installs aren't affected. The fix shipped in v8.6.3 on June 15, and the latest release is v8.8.3. VulnCheck scores it 9.2 Critical (CVSS 4.0) and 8.1 High (CVSS 3.1), while Snipe-IT's advisory rates it Moderate. It isn't in CISA's KEV catalog, and no public exploit or attacks have been reported.

    Microsoft offers voluntary exit to about 60,000 employees

    Microsoft on Monday announced a new Voluntary Exit Offer for eligible employees in participating teams in the US, Canada, India and the UK at level 70 and below. Chief People Officer Amy Coleman's memo says it "builds on what we learned" from April's Voluntary Retirement Program. About 60,000 people, roughly a quarter of its 223,000 staff, are eligible, the company told GeekWire. A person familiar told CNBC that employees decide in December and leave Dec. 31. Some groups, including sales, aren't participating, and Microsoft says the offer doesn't replace layoffs.
