Name of the Vulnerable Software and Affected Versions
curl versions 7.77.0 through 7.85.0
Description
The issue is related to the HSTS check in curl, which can be bypassed to trick it into staying with HTTP. This can happen when the host name in the given URL uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion. For example, using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop of U+002E (.). The earliest affected version is 7.77.0.
Recommendations
For versions 7.77.0 through 7.85.0, update to version 7.86.0 to resolve the issue.
As a temporary workaround, consider avoiding the use of IDN characters in URLs until the issue is resolved.
Restrict access to sensitive information to minimize the risk of exploitation.
