Time for another #LastWeekInAppSec for 12. Aug 2025: ChatGPT-5 system prompt leaked, CISA supports CVE, and AppSec Village completes

πŸ’§πŸ’§ OpenAI released GPT-5 in its ChatGPT platform, but researchers almost immediately discovered and published the ChatGPT5 system prompt, reminding us that system prompts should not contain anything critical or sensitive.

πŸŽ–πŸŽ–οΈ CISA (US Cybersecurity & Infrastructure Security Agency) pleged continued support of the CVE program, an important message after April’s de-funding scare.

πŸ™‚πŸ™‚ The AppSec Village at DEFCON33 ran, with many engaging and educational talks. Keep an eye on the YouTube channel, but be patient – it can take a few months.
