Hacker News - Mon, 09/14/2026 - 4:04pm

We're seeing an explosion of open-source projects.

I created a website helping to compare open-source projects and discover their nearest neighbors in a fun and interactive way. Each point is a project. Project close together tend to be similar.

Cisco Secure Email Gateway SQL Injection Vulnerability

Cisco Security Advisories - Mon, 09/14/2026 - 4:00pm

A vulnerability in the email parsing of Cisco AsyncOS Software for Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to execute arbitrary commands with root privileges on the underlying operating system.

This vulnerability is due to insufficient validation in the email parsing logic. An attacker could exploit this vulnerability by sending a crafted email message that contains malicious SQL statements through an affected device. A successful exploit could allow the attacker to execute arbitrary SQL statements, leading to command execution with root privileges on the underlying operating system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

I started my SaaS 3 months ago and Indian businesses are absuing the free trial

Hacker News - Mon, 09/14/2026 - 2:41pm

I have a b2b product which solves certain problems for marketers.It's called LocalAds

We have been growing organically on Instagram and getting 100s of signups everyday.

But, very few businesses actually want to pay for the product - they will use it for free, get good results but they will not pay.

Infact they log in from a fake account and use our trial plan.

1 dude made 19 trial accounts in a single day.

When we started identifying and blocking these trial accounts the free trial users got mad and started saying "i would have bought if you would have allowed me to make more fake accounts"

None of our international users have given us this problem and happily paid month after month.

Would love to know what should i do to grow this?
