Note, however, that this is generally not sufficient for replacing multi-character strings: the method only performs one pass over the input string, and will not replace further instances of the string that result from earlier replacements.įor example, consider the code snippet s.replace(/\/\.\.\//g, ""), which attempts to strip out all occurences of /./ from s. Otherwise, make sure to use a regular expression with the g flag to ensure that all occurrences are replaced, and remember to escape backslashes if applicable. These libraries are much more likely to handle corner cases correctly than a custom implementation.Īn even safer alternative is to design the application so that sanitization is not needed, for instance by using prepared statements for SQL queries. Use a (well-tested) sanitization library if at all possible. In the latter case, preceding a meta-character with a backslash leads to the backslash being escaped, but the meta-character appearing un-escaped, which again makes the sanitization ineffective.Įven if the escaped string is not used in a security-critical context, incomplete escaping may still have undesirable effects, such as badly rendered or confusing output. In the former case, later meta-characters are left undisturbed and can be used to subvert the sanitization. Common mistakes include only replacing the first occurrence of a meta-character, or backslash-escaping various meta-characters but not the backslash itself. However, directly using the string replace method to perform escaping is notoriously error-prone.

Usually, this is done by escaping meta-characters such as quotes in a domain-specific way so that they are treated as normal characters. Sanitizing untrusted input is a common technique for preventing injection attacks such as SQL injection or cross-site scripting.
