VULNERABILITY FOUND IN SOME POOLS

General Chat
endymionjkb Elokuu 22, 2023, 3.40pm 1

Balancer Labs received a report of a critical vulnerability affecting a number
of pools. We were able to mitigate over 80% of these; the remaining funds at
risk represent about 4% of Balancer TVL.

As of the writing of this post, this vulnerability has not been exploited, and
no funds have been lost.

In response, the Emergency SubDAO acted to enable proportional exit from all
affected pools, and pause any pools still within the pause window.

We believe funds in the mitigated pools (labeled “mitigated”) are safe, but
nevertheless strongly recommend timely migration to safe pools, or withdrawal.
Pools that could not be mitigated are labeled “at risk”. If you are an LP in any
of these pools, please exit immediately.

We’ve provided a personalized page on the user interface to determine whether
the connected wallet is an LP in any affected pools, and a streamlined process
to guide you through withdrawals.

A post-mortem will be published soon with details of the vulnerability and how
it has been addressed.

The full list of pools, for reference, will be provided in a comment on this
post. Go to the withdrawal page and connect your wallet to see whether you are
affected.

What type of pools are vulnerable? We want to make sure forks are not affected.



robert_0211 Elokuu 22, 2023, 5.29pm 7

Are just some boosted pools affected?



nycgirl Elokuu 22, 2023, 5.45pm 9

Withdrew but didn’t get my WETH back in my wallet. Where do I go to find this?

Hello, same here with Avax

The #support channel on the Balancer Discord is the place to go for technical
questions and assistance.



endymionjkb Elokuu 22, 2023, 6.01pm 14

The full list of affected pools is given on the page in the Maxi repo referenced
above. We cannot make a full public disclosure while any funds are still at
risk.

Thanks to the prompt response of the community, and the ease of
migration/withdrawal through the recovery exit page, funds at risk are already
down to ~1.5% of the TVL.

Full details will be provided in the post-mortem.

Hi, i cant enter discord. Balancer discord shows invite expired. I lost part of
my funds on avalanche. Pool Savax-Wavax. stataAvaWAVAX to Wavax was lost 70% of
my funds. No liquidity. What can i do to recuperate?



ative Elokuu 23, 2023, 3.30pm 22

Hi. I can’t withdraw my funds from my account, everything freezes when I click
the withdrawal button. What should I do?



anezick Elokuu 23, 2023, 4.24pm 23

the discord invite not works. how can i deal my problem of lost funds?



ZenDragon Elokuu 23, 2023, 4.54pm 24

dont think your funds are lost, no one lost funds. Would suggest you visit the
aave application and withdraw what you can from there. It takes time to buffer,
but just be sure you are on the right network.



anezick Elokuu 23, 2023, 8.59pm 25

tks, it was solved on discord.

На персонализированной странице в пользовательском интерфейсе не получается
вывести средства. Страница полностью не загружается. Что делать?



Aleks Elokuu 25, 2023, 6.33pm 27

It is not possible to withdraw funds on a personalized page in the user
interface. The page does not load completely. What to do?



cmb_yvr Elokuu 26, 2023, 4.17am 28

Hello
I was in the MaticX-bb-a-WMATIC-BPT-gauge pool…when I withdrew/unwrapped, i only
received back WMATIC and MATICX…missing the underlying coin and cant remember
what it was. I followed all instructions and only received 80% of my total. Is
this issue resolved through discord? ANy support is appreciated.
