Meta is pausing an internal AI training program after sensitive data was accessible across the entire company, according to screenshots obtained by Business Insider.
A screenshot showed that the leak exposed employees' private conversations, performance data, and transcriptions. The incident was classified as a SEV 2 on a scale of 0 to 5, with 0 being the most severe.
A Meta spokesperson confirmed the incident and said the company is investigating.
"We have carefully designed this program with privacy safeguards, and while we have no indication at this time that any data was improperly accessed by Meta employees, we're pausing it while we investigate," the spokesperson said.
In April, Meta announced the AI training program, called the Model Capability Initiative (MCI), which was intended to improve the company's AI models by using its staff's keystrokes and mouse movements as training data. The program, which is mandatory for most staff, sparked a backlash from employees who felt uncomfortable with their data being recorded, Business Insider previously reported.
This leak is causing frustration within Meta, according to screenshots seen by Business Insider, with employees critical that data wasn't locked down from the start.
"I am incensed," one employee wrote on Monday about the recent leak in an internal group, according to a screenshot obtained by Business Insider.
"I don't see any evidence of malicious access, but the fact that this data wasn't locked down as originally promised is super frustrating," the employee continued.
The leak is the latest in a string of recent security incidents for Meta. Last month, a flaw in its AI chatbot allowed people to hijack multiple Instagram accounts. A rogue AI agent also caused a severe incident in March, the Information reported.
Correction: June 22, 2026 — An earlier version of this story misstated Meta's severity scale. 0 is the most severe on its scale.
