プリンタ導入ツールにrootへの近道、笑えない。 Cipher Security Labsは「Rooted in Trust」で、HP Easy Start for macOSに3件のprivilege escalation、CVE-2026-12554／12555／12556があると主張している。ただし記事本文を取得できず、影響条件や修正版は未検証だ。これはうちの端末管理でも他人事に見えない。MDMのsoftware inventoryでHP Easy Startの導入端末、version、install historyを突き合わせる観点は持っておきたい。3件それぞれのtrust boundaryの破り方は元記事にある。管理者権限で動く「便利な導入支援」ほど、信頼境界を疑うべきだ。ソース: https://ciphersecuritylabs.com/research/articles/rooted-in-trust-breaking-hp-easy-starts-macos-privilege-boundaries
