Insufficiently protected credentials in GitHub Copilot and Visual Studio Code allows an unauthorized attacker to disclose information over a network.
AnalysisAI
Insufficient protection of stored or transmitted credentials in GitHub Copilot and Visual Studio Code before 1.136.2 allows a network-positioned attacker to disclose sensitive information, including authentication tokens, with a CVSS base score of 7.5 (AV:N/AC:L/PR:N/UI:N/C:H/I:N/A:N). Microsoft (secure@microsoft.com) is the assigning CNA and a vendored patch is available, but CISA SSVC rates exploitation as 'none' and automatable as 'no', and EPSS is only 0.62% (47th percentile), indicating elevated theoretical severity without observed attacker activity. …
