# CVE-2024-21669: Hyperledger Aries Cloud Agent Python result of presentation verification not checked for LDP-VC

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6% , percentile 50: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 50% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes aries-cloudagent (PyPI) >= 0.7.0, < 0.10.5, fixed in 0.10.5 ; aries-cloudagent (PyPI) >= 0.11.0rc1, < 0.11.0, fixed in 0.11.0 . Check your lockfile, including transitive dependencies.

## What it is

Hyperledger Aries Cloud Agent Python (ACA-Py) is a foundation for building decentralized identity applications and services running in non-mobile environments. When verifying W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs (LDP-VCs), the result of verifying the presentation document.proof was not factored into the final verified value (true/false) on the presentation record. The flaw enables holders of W3C Format Verifiable Credentials using JSON-LD with Linked Data Proofs (LDPs) to present incorrectly constructed proofs, and allows malicious verifiers to save and replay a presentation from such holders as their own. This vulnerability has been present since version 0.7.0 and fixed in version 0.10.5.

## Affected packages

- PyPI `aries-cloudagent` >= 0.7.0, < 0.10.5 → fixed: 0.10.5
- PyPI `aries-cloudagent` >= 0.11.0rc1, < 0.11.0 → fixed: 0.11.0

## Affected products (CVE record)

- hyperledger aries-cloudagent-python: >= 0.7.0, < 0.10.5, >= 0.11.0rc1, < 0.11.0

## Severity

- GitHub_M CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L`
- GitHub CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.63% probability of exploitation activity in the next 30 days; percentile 50.
