# The curl bug bounty

The curl project runs a bug bounty program in association with
[HackerOne](https://www.hackerone.com/).

# How does it work?

Start out by posting your suspected security vulnerability directly to [curl's
hackerone security bug tracker](https://www.hackerone.com/curl).

After you have reported a security issue, 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://hackerone.com/curl](https://hackerone.com/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 that is rewarded depends on how
serious the flaw is determined to be.

We offer reward money *up to* a certain amount per severity. The curl security
team determines the severity of each reported flaw on a case by case basis and
the exact amount rewarded to the reporter is then decided.

At the start of the program, the award amounts are:

 Critical: 2,000 USD
 High:     1,500 USD
 Medium:   1,000 USD
 Low:        500 USD

# 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.

Vulnerabilities in features which are off by default and documented as
experimental, are not eligible for a reward.

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.

The vulnerabilities must not have been made public before February 1st, 2019.
We do not retroactively pay for old, already known and published security
problems.

# Product vulnerabilities only

This 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 we set an amount depending on the specifics of
the individual case. Other sponsors of the program might also get involved and
can raise the amounts depending on the particular issue.

# 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 to work out and
handle together with hackerone. The curl project or its security team never
actually receive any of this money, hold the money or pay out the money.
