DO NOT CREATE A GITHUB ISSUE to report a security problem.
Instead please email anchor-security@solana.org. Provide a helpful title, detailed description of the vulnerability and an exploit proof-of-concept. Speculative submissions without proof-of-concept will be closed with no further consideration.
If you haven't done so already, please enable two-factor auth in your GitHub account.
Expect a response as fast as possible in the advisory, typically within 72 hours.
As a general rule of thumb, we will look to these questions to evaluate eligibility:
Regardless, if you think you have an issue, we'd like to hear about it.
For bugs that affect production code, we will pay up to $X according to the following guidelines. This is exclusive to any bounties claimed from the protocol. In other words, reports can't double-dip.
If you do not receive a response in the advisory, send an email to anchor-security@solana.org with the full URL of the advisory you have created. DO NOT include attachments or provide detail sufficient for exploitation regarding the security issue in this email. Only provide such details in the advisory.
In case an incident is discovered or reported, the following process will be followed to contain, respond and remediate:
In response a newly reported security problem, a member of the solana-foundation/admins group will accept the report to turn it into a draft advisory. The solana-foundation/anchor-security-incident-response group should be added to the draft security advisory, and create a private fork of the repository (grey button towards the bottom of the page) if necessary.
If the advisory is the result of an audit finding, follow the same process as above but add the auditor's github user(s) and begin the title with "[Audit]".
If the report is out of scope, a member of the solana-foundation/admins group will comment as such and then close the report.
Within the draft security advisory, discuss and determine the severity of the issue. If necessary, members of the solana-foundation/anchor-security-incident-response group may add other github users to the advisory to assist. If it is determined that this is not a critical Anchor issue then the advisory should be closed and if more follow-up is required a normal Anchor public github issue should be created.
For the affected branches, typically all three (edge, beta and stable), prepare a fix for the issue and push them to the corresponding branch in the private repository associated with the draft security advisory. There is no CI available in the private repository so you must build from source and manually verify fixes. Code review from the reporter is ideal, as well as from multiple members of the core development team.
Once an ETA is available for the fix, a member of the solana-foundation/anchor-security-incident-response group should notify major affected parties. The teams are all over the world and it's critical to provide actionable information at the right time. Don't be the person that wakes everybody up at 2am when a fix won't be available for hours.
Once the fix is accepted it may be distributed directly to developers as a patch, depending on the vulnerability.
Once the fix has been deployed to major affected parties, the patches from the security advisory may be merged into the main source repository. A new official release for each affected branch should be shipped and all parties requested to upgrade as quickly as possible.
If this issue is eligible for a bounty, prefix the title of the security advisory with one of the following, depending on the severity:
Confirm with the reporter that they agree with the severity assessment, and discuss as required to reach a conclusion.
We currently do not use the Github workflow to publish security advisories. Once the issue and fix have been disclosed, and a bounty category is assessed if appropriate, the GitHub security advisory is no longer needed and can be closed.
At its sole discretion, the Solana Foundation may offer a bounty for valid reports of Anchor vulnerabilities. Please see below for more details. The submitter is not required to provide a mitigation to qualify.
Note: Payments will continue to be paid out in 12-month locked SOL.
Max: $100k in SOL tokens. Min: $10k in SOL tokens
Max: $25k in SOL tokens. Min: $5k in SOL tokens
Max: $5k in SOL tokens. Min: $100 in SOL tokens
The following components are out of scope for the bounty program
Compensation for duplicative reports will be split among reporters with first to report taking priority using the following equation:
R: total reports ri: report priority bi: bounty share
bi = 2 ^ (R - ri) / ((2^R) - 1)
| total reports | priority | share |
|---|---|---|
| 1 | 1 | 100% |
| 2 | 1 | 66.67% |
