Operationally, ranked in the top 7.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The vulnerability CVE-2023-2859 is a code injection issue, tracked as CWE-94, that affects the nilsteampassnet/teampass repository prior to version 3.0.9. It received a CVSS 3.1 score of 8.8 reflecting a network attack vector, low attack complexity, no required privileges, and required user interaction, with high impact on confidentiality, integrity, and availability.
An unauthenticated remote attacker who can induce a user to perform a specific action may exploit the flaw to inject and execute arbitrary code within the TeamPass application.
The referenced GitHub commit 1f51482a0c4d152ca876844212b0f8f3cb9387af implements the fix, and the associated huntr.dev reports indicate that mitigation consists of upgrading to TeamPass 3.0.9 or later.
The EPSS score has remained flat at a peak of 0.0867 with no material rise after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
