SUSE CVE-2026-68497

jackson-databind binds a JSON string to a javax.xml.datatype.Duration or javax.xml.datatype.XMLGregorianCalendar field by passing the raw string verbatim to DatatypeFactory.newDurationvalue or newXMLGregorianCalendarvalue in CoreXMLDeserializers.Std.deserialize. These deserializers are registered...

Denial Of Service (DoS)

Spring Framework is vulnerable to Denial of Service DoS. The vulnerability is due to inefficient processing of the SpEL power operator ^ with BigDecimal or BigInteger operands and large exponent values, which allows an attacker to supply a crafted expression that consumes excessive CPU and memory...
