Security fixes are made on the main branch and in the latest
release. Older releases are not updated.
Please don't report security problems in public issues.
Report them privately through GitHub instead: open this repository's Security tab and choose Report a vulnerability. Only the repository's maintainers can see the report.
Please include:
- the cputty version (
plink -V, or the About box on Windows) and your operating system; - what an attacker could do, and what they need to do it (for example, control of the SSH server you connect to, or access to your machine);
- steps to reproduce the problem, or a proof of concept.
cputty is a fork of PuTTY. If the problem is in code that cputty hasn't changed, official PuTTY is probably affected too, so please also report it to the PuTTY developers. Their feedback page explains how, under "Reporting security vulnerabilities": https://www.chiark.greenend.org.uk/~sgtatham/putty/feedback.html
