Exif Smuggling: PoC for Hiding Malicious Prompts in Image EXIF Metadata
Hacker News (AI keywords)·yesterday·Incident
Exif Smuggling is a security PoC showing how attackers can embed hidden instructions in image EXIF metadata fields to perform indirect prompt injection against vision-capable AI models. When AI systems parse images alongside their metadata, embedded malicious text may be processed as legitimate instructions, bypassing standard input filters. Developers building AI apps with image upload features should strip or sanitize EXIF data before passing content to language models.
