LinkedIn (Microsoft)

The 'BrowserGate' report (April 2026, published by Fairlinked e.V., an association of commercial LinkedIn users) alleged that every time you load LinkedIn on a Chrome-based browser, hidden code silently checks for over 6,000 SPECIFIC BROWSER EXTENSIONS with no visible indicator or consent request; BleepingComputer's own testing found a script checking for 6,236 extensions, and LinkedIn acknowledges detecting 'over 6,000' but says it does so to identify scraping tools. The script also collects device characteristics (CPU cores, memory, screen resolution, timezone, battery status and more) that can be used for fingerprinting. Because LinkedIn ties every profile to a REAL NAME, employer, and job title, the researchers argue this scan could link a person's religious beliefs, political leanings, or health-related tool use to their professional identity; LinkedIn says it does not use the data to infer sensitive information. This sits on top of a SEPARATE January 2025 lawsuit — reportedly dropped by the plaintiff shortly after filing — that had alleged LinkedIn quietly opted Premium users into sharing their PRIVATE MESSAGES for AI training, then rewrote its own FAQ afterward in a way the lawsuit calls an attempt to 'cover its tracks' — and even where LinkedIn now lets you opt out going forward, it has NOT offered to delete your data from AI models already trained on it.

Data sharing

MULTIPLE 2025-2026 CLASS ACTIONS (status not re-verified as of Oct 2026; one was voluntarily dropped, see (3)): (1) a proposed class action (Ganan v. LinkedIn, N.D. Cal., filed April 7, 2026) alleges LinkedIn uses hidden scripts to scan users' installed BROWSER EXTENSIONS and fingerprint devices, sending the results to LinkedIn's servers — researchers contend the data could hint at political views, religious beliefs, health conditions and job searches tied to real identities, done silently on every page load without disclosure in the privacy policy; (2) LinkedIn's own 'LinkedIn Insight Tag' tracking pixel has reportedly been named as a CO-DEFENDANT (alongside Meta) in healthcare-website privacy lawsuits (specific case not independently verified) for allegedly intercepting and transmitting sensitive patient information (e.g., fertility treatment type, sexual orientation) to LinkedIn/Meta for ad-targeting without consent — meaning LinkedIn's tracking infrastructure creates legal exposure even on THIRD-PARTY websites having nothing to do with LinkedIn itself; (3) a January 2025 class action alleged LinkedIn shared PAID PREMIUM subscribers' private messages (about employment, IP, and compensation) with third parties to train AI models, breaching a premium contract that promised heightened privacy — the plaintiff reportedly voluntarily DROPPED this suit shortly after filing, after LinkedIn said it had not used premium messages for AI training (exact timing not re-verified), illustrating that not every well-publicized privacy allegation holds up once challenged.
