DO NOT CREATE A GITHUB ISSUE to report a security problem.
Instead please use this Report a Vulnerability link. 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.

If you do not receive a response in the advisory, send an email to security@solanalabs.com 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.
If you do not receive a response from security@solanalabs.com please follow up with the team directly. You can do this in the #web3js channel of the Solana Tech discord server, by pinging the Solana Labs role in the channel and referencing the fact that you submitted a security problem.
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-labs/admins group will accept the report to turn it into a draft advisory. The solana-labs/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-labs/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-labs/security-incident-response group may add other github users to the advisory to assist. If it is determined that this is not a critical issue then the advisory should be closed and if more follow-up is required a normal Solana public github issue should be created.
Prepare a fix for the issue and push them to master 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 the fix is accepted, a member of the solana-labs/security-incident-response group should prepare a patch using pnpm patch, yarn patch, and patch-package for developers still using npm. Post the patch to an unlisted GitHub Gist and disseminate patch instructions privately to as many vulnerable applications as possible.
Once the fix has been deployed to as large an affected application set as practical, the patches from the security advisory may be merged into the main source repository. A new official release should be shipped, and old affected releases deprecated on NPM using the npm deprecate command.
