ChatGPT Flaw Could Let Attackers Steal Gmail Data Across User Accounts

Check Point found a patched ChatGPT flaw where prompt injection and a shared Artifactory service let attackers covertly exfiltrate Gmail data across accounts.

Check Point Research discovered that ChatGPT's isolated code-execution containers could access a shared internal JFrog Artifactory service, whose item metadata API enabled a bidirectional cross-tenant covert channel between accounts. Attackers could embed hidden prompt-injection instructions in shared conversations or custom GPT configurations, causing a victim's session to silently relay connected Gmail data to another ChatGPT account. In a proof of concept, email data was exfiltrated with the only visible hint being a 'Talked to Gmail' activity label. OpenAI decommissioned the internal Artifactory instance involved, eliminating the channel by publication time.

A Deep Dive Into Attempted Exploitation of CVE-2023

Mirai-like botnet scans exploit TP-Link EOL router flaw CVE-2023-33538 after CISA KEV addition, though observed exploit code is flawed.

Unit 42 observed large-scale automated scans attempting to exploit CVE-2023-33538 in end-of-life TP-Link TL-WR940N, TL-WR740N and TL-WR841N routers after CISA added the flaw to its KEV catalog in June 2025. HTTP GET requests inject commands via the ssid1 parameter at the /userRpm/WlanNetworkRpm endpoint to download and execute an arm7 ELF binary, a Mirai variant related to the Condi IoT botnet. Firmware emulation and reverse engineering showed the observed exploits are flawed and would fail, but the underlying vulnerability is real and successful exploitation requires authentication to the router's web interface. TP-Link confirmed the devices are end-of-life with no patches available and recommends replacing units and eliminating default credentials.
