CVE-2022-36447
HIGHchia-blockchain tokens can be inflated to an arbitrary extent
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
An inflation issue was discovered in Chia Network CAT1 Standard 1.0.0. Previously minted tokens minted on the Chia blockchain using the CAT1 standard can be inflated to an arbitrary extent by any holder of any amount of the token. The total amount of the token can be increased as high as the malicious actor pleases. This is true for every CAT1 on the Chia blockchain regardless of issuance rules. This attack is auditable on chain, so maliciously altered coins can potentially be marked by off-chain observers as malicious.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for chia-blockchain. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of chia-blockchain has shipped for CVE-2022-36447 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2022-36447 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2022-36447. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-36447 in your dependencies?
O3 detects CVE-2022-36447 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
