Exif Smuggling: PoC for Hiding Malicious Prompts in Image EXIF Metadata
Original: Exif Smuggling
A proof-of-concept tool demonstrating how malicious instructions can be smuggled into image EXIF metadata to attack multimodal AI systems via prompt injection.
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.
"Exif Smuggling" is a Proof of Concept project published on GitHub by security researcher signalblur. Its core topic is to use EXIF metadata from image files as a medium to carry out prompt injection attacks on multimodal AI systems.
