      <title>CVE-2021-48018 — Vyper 0.2.13 before 0.2.15 Storage Corruption via @nonreentrant Decorator</title>
      <link>https://db.gcve.eu/vuln/cve-2021-48018</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; vyperlang vyper&lt;/p&gt;
&lt;p&gt;Vyper from 0.2.13 before 0.2.15 allocates storage slots for @nonreentrant reentrancy locks at the same locations as contract storage variables. When a function using @nonreentrant is called, setting the lock overwrites the overlapping storage variable, corrupting contract state and breaking the contract&amp;#39;s intended logic.&lt;/p&gt;</description>
