CVE-2026-27596 | Exiv2: Integer Underflow in LoaderNative::getData() Causes Heap Buffer Overflow

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found in Exiv2. The vulnerability is in the preview component, which is only triggered when running Exiv2 with an extra command line argument, like -pp. The out-of-bounds read is at a 4GB offset, which usually causes Exiv2 to crash. This issue has been patched in version 0.28.8.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
