The curl bug bounty
The curl project runs a bug bounty program in association with bountygraph.com.
After you have reported a security issue to the curl project, it has been deemed credible and a patch and advisory has been made public you can be eligible for a bounty from this program.
See all details at https://bountygraph.com/programs/curl
This bounty is relying on funds from sponsors. If you use curl professionally, consider help funding this!
How much money is the bounty at
The curl projects offer monetary compensation for reported and published security vulnerabilities. The amount of money rewarded depends on how serious the flaw is determined to be.
We offer reward money up to these amounts. The curl security team will solely and exclusively determine the exact amount for each reported flaw on a case by case basis and keep the rights to adjust the amount as it sees fit.
- Low USD 500
- Medium USD 1,000
- High USD 5,000
- Critical USD 10,000
Who's eligible for a reward
Everyone and anyone who reports a security problem in a released curl version that hasn't already been reported can ask for a bounty.
The vulnerability has to be fixed and publicly announced (by the curl project) before a bug bounty will be considered.
Bounties need to be requested within twelve months from the publication of the vulnerability.
Product vulnerabilities only
The bug bounty only concerns the curl and libcurl products and thus their respective source codes - when running on existing hardware. It does not include documentation, web sites or other infrastructure.
The curl security team will be the sole arbiter if a reported flaw can be subject to a bounty or not.
How are vulnerabilities graded
The grading of each reported vulnerability that makes a reward claim will be performed by the curl security team. The grading will be based on the CVSS (Common Vulnerability Scoring System) 3.0.
How are reward amounts determined
The curl security team first gives the vulnerability a score, as mentioned above, and based on that level the team may increase or decrease the bounty amount from the general template depending on the specifics of the individual case.
The curl security team will be the sole arbiter of the bounty amount.
What happens if the bounty fund is drained
The bounty fund depends on sponsors. If we pay out more bounties than we add, the fund will eventually drain. If that end up happening, we will simply not be able to pay out as high bounties as we would like and hope that we can convince new sponsors to help us top up the fund again.
Regarding taxes etc on the bounties
In the event that the individual receiving a curl bug bounty needs to pay taxes on the reward money, that's something for the receiver (and bountygraph.com?) to work out and handle. The curl project or its security team never actually receive any of this money, hold the money or pay out the money.
