Lynx Project Security Vulnerabilities

CVE-1999-1549

Lynx 2.x does not properly distinguish between internal and external HTML, which may allow a local attacker to read a "secure" hidden form value from a temporary file and craft a LYNXOPTIONS: URL that causes Lynx to modify the user's configuration file and execute commands.

CVE-2014-5002

The lynx gem before 1.0.0 for Ruby places the configured password on command lines, which allows local users to obtain sensitive information by listing processes.

CVE-2017-1000211

Lynx before 2.8.9dev.16 is vulnerable to a use after free in the HTML parser resulting in memory disclosure, because HTML_put_string() can append a chunk onto itself.

CVE-2021-38165

Lynx through 2.8.9 mishandles the userinfo subcomponent of a URI, which allows remote attackers to discover cleartext credentials because they may appear in SNI data.
