Block stuffing for profit

Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)

Theft of unclaimed yield due to Harvest contract issue

Permanent freezing of unclaimed yield due to Harvest contract issue

Incorrect modification of user data

Leaking user data

Changing non-sensitive details of other users (including modifying browser local storage) without already-connected wallet interaction and with up to one click of user interaction, such as changing the name of a user, or enabling/disabling notifications

Injecting/modifying the static content on the target application without Javascript (Reflected) such as reflected HTML injection or loading external site data

Redirecting users to malicious websites (open redirect)

Any governance voting result manipulation

Direct theft of any user funds, whether at rest or in motion, other than unclaimed yield

Permanent freezing of funds

Deletion of site data

XSS/CSRF

Execute arbitrary system commands

Retrieve sensitive data/files from a running server such as /etc/shadow, database passwords, and blockchain keys(this does not include non-sensitive environment variables, open source code, or usernames)

Taking down the application/website

Taking state-modifying authenticated actions (with or without blockchain state interaction) on behalf of other users without any interaction by that user, such as, changing registration information, commenting, voting, making trades, withdrawals, etc

Subdomain takeover with already-connected wallet interaction

Direct theft of user funds

Malicious interactions with an already-connected wallet such as modifying transaction arguments or parameters, substituting contract addresses, submitting malicious transactions

Rewards are distributed according to the impact of the vulnerability based on
the [Immunefi Vulnerability Severity Classification System](/severity-system/). This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from the consequence of exploitation to the privilege required to the likelihood of a successful exploit. 

The final reward amount for critical smart contract bugs is capped at 10% of 
economic damage based on the vulnerability reported with a minimum payout of 
**USD 50 000**.

Theft of yield/interest is considered as Medium for this bug bounty program.

All smart contract reports must include a PoC to be accepted. The PoC should provide clear proof of the vulnerability in a locally forked blockchain environment. All bug reports without a PoC will be rejected and require the submitter to resubmit with a PoC. 

The following table is used for the classification of web and app bug reports. In the event of conflict with the Immunefi Vulnerability Severity Classification System, the classification on this table will be what is considered.

| Severity | Vulnerability |
| :-- | :-: |
| **Critical** | Deletion of site data, XSS/CSRF, ACE |
| **High** | Denial of Service, DoS ampliciation |
| **Medium** | Incorrect modification of user data, leaking user data |

All web and app bug reports must include a PoC to be accepted. All web and app bug reports without a PoC will be rejected and require the submitter to resubmit with a PoC. 

Vulnerabilities that require moderator-approved access to be exploited will only receive a maximum of 20% of the advertised reward. For Critical Smart Contract and Blockchain vulnerability reports, this 20% is applied after the cap of 10% of economic damage.  

Payouts are handled by the **Harvest Finance** team directly and are denominated in USD. Payouts up to **USD 100 000** are paid in **USDC**.
