CVE-2023-34047 | Exposure of data and identity to wrong session in Spring for GraphQL

A batch loader function in Spring for GraphQL versions 1.1.0 - 1.1.5 and 1.2.0 - 1.2.2 may be exposed to GraphQL context with values, including security context values, from a different session. An application is vulnerable if it provides a DataLoaderOptions instance when registering batch loader functions through DefaultBatchLoaderRegistry.

3.1 3.1 LOW
CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N Click to expand
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:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
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:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
