All the vulnerabilities related to the version 0.5.2 of the package
Open Redirect in ecstatic
Versions of ecstatic prior to 4.1.2, 3.3.2 or 2.2.2 are vulnerable to Open Redirect. The package fails to validate redirects, allowing attackers to craft requests that result in an HTTP 301 redirect to any other domains.
If using ecstatic 4.x, upgrade to 4.1.2 or later.
If using ecstatic 3.x, upgrade to 3.3.2 or later.
If using ecstatic 2.x, upgrade to 2.2.2 or later.
Denial of Service in ecstatic
ecstatic have a denial of service vulnerability. Successful exploitation could lead to crash of an application.
Denial of Service in ecstatic
ecstatic, a simple static file server middleware, is vulnerable to denial of service. If a payload with a large number of null bytes (%00) is provided by an attacker it can crash ecstatic by running it out of memory.
Results from the original advisory
A payload of 22kB caused a lag of 1 second,
A payload of 35kB caused a lag of 3 seconds,
A payload of 86kB caused the server to crash
Update to version 2.0.0 or later.
Denial of Service in ecstatic
Versions of ecstatic prior to 1.4.0 are affected by a denial of service vulnerability when certain input strings are sent via the Last-Modified or If-Modified-Since headers.
Parsing certain inputs with new Date() or Date.parse() cases v8 to crash. As ecstatic passes the value of the affected headers into one of these functions, sending certain inputs via one of the headers will cause the server to crash.
Update to version 1.4.0 or later.
mime Regular Expression Denial of Service when MIME lookup performed on untrusted user input
Affected versions of mime are vulnerable to regular expression denial of service when a mime lookup is performed on untrusted user input.
Update to version 2.0.3 or later.
Prototype Pollution in minimist
Affected versions of minimist are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of Object, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument --__proto__.y=Polluted adds a y property with value Polluted to all objects. The argument --__proto__=Polluted raises and uncaught error and crashes the application.
This is exploitable if attackers have control over the arguments being passed to minimist.
Upgrade to versions 0.2.1, 1.2.3 or later.
Prototype Pollution in minimist
Minimist prior to 1.2.6 and 0.2.4 is vulnerable to Prototype Pollution via file index.js, function setKey() (lines 69-95).
