Nearly 520 people working at UK military bases have shared their exercise routes and locations on the running app Strava, the i Paper reports.
Reporters were able to track one individual to the exact nuclear submarine they were working on.
The Strava app, which has over 180 million users worldwide, uses GPS tracking to monitor activities like running and cycling, allowing users to share the routes they have taken.
Since January, 110 people have used Strava while running at Faslane naval base on the Clyde, home of the UK's Trident nuclear missiles.

Staff at RAF Akrotiri in Cyprus and Diego Garcia in the Indian Ocean, which both house US bombers striking Iran, were also exposed through the app.
The data from Strava would allow anyone to identify who was working at which base, and potentially track classified deployments abroad.
A spokesperson from the Ministry of Defence said the use of fitness apps like Strava is not considered an operational threat and that the locations of bases are in the public domain.
"We take the security of our personnel very seriously and keep guidance for them under constant review," they added.
Conservative MP Ben Obese-Jecty, a former army officer, wrote on X: "I stopped using Strava when I became an MP and I locked down my profile long before that.
"The app has numerous features to enable you to keep your data private.
"It beggars belief that our armed forces don't have a grip of this given the current, and very real, threat posed by sub-threshold activity from our adversaries."
