Decompression bomb (data amplification) in ExifReader npm package before 4.39.0 allows remote unauthenticated attackers to exhaust server memory by supplying a crafted PNG file with a highly compressed zTXt metadata chunk. The vulnerable path activates only when the caller enables asynchronous parsing (`async: true`), at which point ExifReader decompresses the chunk via the Compression Streams API with no upper bound on output size. Publicly available proof-of-concept exploit code exists (E:P); this CVE is not listed in CISA KEV.
Denial-of-service in ExifReader (npm package mattiasw/ExifReader) before 4.39.0 allows remote attackers to exhaust memory by submitting a crafted image whose ICC profile contains a malformed mluc tag. A specially crafted record count combined with a zero record size causes the parser to loop on the same record while continuously appending entries to an array, driving memory growth until the host process crashes. CVSS 4.0 base score is 7.7 with proof-of-concept exploit maturity (E:P), and publicly available exploit code exists via the referenced gist; no active in-the-wild exploitation is indicated.
