CVE-2021-22925
En bref Sévérité MEDIUM 5.3 EPSS EPSS 5.37 % · centile 93 (2026-10-27) État PUBLISHED Publiée 2021-08-05 Mise à jour 2026-10-14 Attribuée par hackerone Statut NVD Modified Description curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application.
