CVE-2025-49597 | handcraftedinthealps goodby-csv Potential Gadget Chain allowing Remote Code Execution

handcraftedinthealps goodby-csv is a highly memory efficient, flexible and extendable open-source CSV import/export library. Prior to 1.4.3, goodby-csv could be used as part of a chain of methods that is exploitable when an insecure deserialization vulnerability exists in an application. This so-called "gadget chain" presents no direct threat but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability. The problem is patched with Version 1.4.3.

3.9 3.1 LOW
CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:L Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
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:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
