The lesson from this incident

Full lesson

CVE-2026-118539 exposes a critical flaw in Drupal's Commerce Core module where missing authorization checks allow attackers to bypass access controls entirely. This means unauthenticated or low-privileged users can perform actions reserved for administrators, directly threatening the financial integrity of online stores. Active exploitation in the wild means that unpatched sites are already being targeted, not just theoretically at risk. The root failure is twofold: the module shipped without adequate authorization enforcement, and site operators failed to apply the patch before attackers weaponized the vulnerability.
