California's Medicaid health-assistance program, Medi-Cal, told customers this week that it had accidentally published the Social Security numbers of 14,000 individuals affiliated with the program.
The highly personal information, which also included names, care information and home addresses, remained up on a government site for at least nine days before it was removed on Nov. 14, Kaspersky's Threatpost blog reported.
The leaked data affects In-Home Supportive Services (IHSS) providers in 25 California counties, Sacramento's KCRA-TV reported.
California law obliges state agencies to notify affected residents when data breaches occur. If the breach impacts more than 500 Californians, agencies must also disclose the breach to the state attorney general.
Those affected will be provided with credit-monitoring services from Experian.
Recently, California has seen at least two other data breaches that affect the medical community.
A May data breach at the Department of Social Services exposed the personally identifiable information of 750,000 persons. Last year, a smaller breach at IHSS leaked the personal information of 2,400 beneficiaries.
